If fastReceiver() took more than 0.01 seconds to exit,

-  What is EPICS base?
-
-     The Experimental Physics and Industrial Control Systems (EPICS) is an
-     extensible set of software components and tools with which application
-     developers can create a control system. This control system can be used
-     to control accelerators, detectors, telescopes, or other scientific
-     experimental equipment. EPICS base is the set of core software, i.e. the
-     components of EPICS without which EPICS would not function. EPICS base
-     allows an arbitrary number of target systems, IOCs (input/output
-     controllers), and host systems, OPIs (operator interfaces) of various
-     types.
-
-  What is new in this release?
-
-     Please check the RELEASE_NOTES file in the distribution for description
-     of changes and release migration details.
-
-  Copyright
-
-     Please review the LICENSE file included in the distribution for legal
-     terms of usage.
-
-  Supported platforms
-
-     The list of platforms supported by this version of EPICS base is given
-     in the configure/CONFIG_SITE file. If you are trying to build EPICS Base
-     on an unlisted host or for a different target machine you must have the
-     proper host/target cross compiler and header files, and you will have to
-     create and add the appropriate new configure files to the
-     base/configure/os/directory. You can start by copying existing
-     configuration files in the configure/os directory and then make changes
-     for your new platforms.
-
-  Supported compilers
-
-     This version of EPICS base has been built and tested using the host
-     vendor's C and C++ compilers, as well as the GNU gcc and g++ compilers.
-     The GNU cross-compilers work for all cross-compiled targets. You may
-     need the C and C++ compilers to be in your search path to do EPICS
-     builds; check the definitions of CC and CCC in
-     base/configure/os/CONFIG.<host>.<host> if you have problems.
-
-  Software requirements
-
-     GNU make
-     You must use GNU make, gnumake, for any EPICS builds. Set your path so
-     that a gnumake version 3.81 or later is available.
-
-     Perl
-     You must have Perl version 5.8.1 or later installed. The EPICS
-     configuration files do not specify the perl full pathname, so the perl
-     executable must be found through your normal search path.
-
-     Unzip and tar (Winzip on WIN32 systems)
-     You must have tools available to unzip and untar the EPICS base
-     distribution file.
-
-     Target systems
-     EPICS supports IOCs running on embedded platforms such as VxWorks and
-     RTEMS built using a cross-compiler, and also supports soft IOCs running
-     as processes on the host platform.
-
-     vxWorks
-     You must have vxWorks 5.5.x or 6.x installed if any of your target
-     systems are vxWorks systems; the C++ compiler for vxWorks 5.4 is now too
-     old to support. The vxWorks installation provides the cross-compiler and
-     header files needed to build for these targets. The absolute path to and
-     the version number of the vxWorks installation must be set in the
-     base/configure/os/CONFIG_SITE.Common.vxWorksCommon file or in one of its
-     target-specific overrides.
-
-     Consult the vxWorks 5.x or vxWorks 6.x EPICS web pages about and the
-     vxWorks documentation for information about configuring your vxWorks
-     operating system for use with EPICS.
-
-     RTEMS
-     For RTEMS targets, you need RTEMS core and toolset version 4.9.2 or
-     later.
-
-     GNU readline or Tecla library
-     GNU readline and Tecla libraries can be used by the IOC shell to provide
-     command line editing and command line history recall and edit. GNU
-     readline (or Tecla library) must be installed on your target system when
-     COMMANDLINE_LIBRARY is set to READLINE (or TECLA) for that target. EPICS
-     (EPICS shell) is the default specified in CONFIG_COMMON. A READLINE
-     override is defined for linux-x86 in the EPICS distribution. Comment out
-     COMMANDLINE_LIBRARY=READLINE in
-     configure/os/CONFIG_SITE.Common.linux-x86 if readline is not installed
-     on linux-x86. Command-line editing and history will then be those
-     supplied by the os. On vxWorks the ledLib command-line input library is
-     used instead.
-
-  Host system storage requirements
-
-     The compressed tar file is approximately 1.6 MB in size. The
-     distribution source tree takes up approximately 12 MB. Each host target
-     will need around 40 MB for build files, and each cross-compiled target
-     around 20 MB.
-
-  Documentation
-
-     EPICS documentation is available through the EPICS website at Argonne.
-
-     Release specific documentation can also be found in the
-     base/documentation directory of the distribution.

-
-  Building EPICS base (Unix and Win32)
-
-    Unpack file
-
-       Unzip and untar the distribution file. Use WinZip on Windows systems.
-
-    Set environment variables
-
-       Files in the base/startup directory have been provided to help set
-       required path and other environment variables.
-
-       EPICS_HOST_ARCH
-       Before you can build or use EPICS R3.15, the environment variable
-       EPICS_HOST_ARCH must be defined. A perl script EpicsHostArch.pl in the
-       base/startup directory has been provided to help set EPICS_HOST_ARCH.
-       You should have EPICS_HOST_ARCH set to your host operating system
-       followed by a dash and then your host architecture, e.g.
-       solaris-sparc. If you are not using the OS vendor's c/c++ compiler for
-       host builds, you will need another dash followed by the alternate
-       compiler name (e.g. "-gnu" for GNU c/c++ compilers on a solaris host
-       or "-mingw" for MinGW c/c++ compilers on a WIN32 host). See
-       configure/CONFIG_SITE for a list of supported EPICS_HOST_ARCH values.
-
-       PERLLIB
-       On WIN32, some versions of Perl require that the environment variable
-       PERLLIB be set to <perl directory location>.
-
-       PATH
-       As already mentioned, you must have the perl executable and you may
-       need C and C++ compilers in your search path. For building base you
-       also must have echo in your search path. For Unix host builds you also
-       need ln, cpp, cp, rm, mv, and mkdir in your search path and /bin/chmod
-       must exist. On some Unix systems you may also need ar and ranlib in
-       your path, and the C compiler may require as and ld in your path. On
-       solaris systems you need uname in your path.
-
-       LD_LIBRARY_PATH
-       R3.15 shared libraries and executables normally contain the full path
-       to any libraries they require. However, if you move the EPICS files or
-       directories from their build-time location then in order for the
-       shared libraries to be found at runtime LD_LIBRARY_PATH must include
-       the full pathname to $(INSTALL_LOCATION)/lib/$(EPICS_HOST_ARCH) when
-       invoking executables, or some equivalent OS-specific mechanism (such
-       as /etc/ld.so.conf on Linux) must be used. Shared libraries are now
-       built by default on all Unix type hosts.
-
-    Do site-specific build configuration
-
-       Site configuration
-       To configure EPICS, you may want to modify the default definitions in
-       the following files:
-
-         configure/CONFIG_SITE      Build choices. Specify target archs.
-         configure/CONFIG_SITE_ENV  Environment variable defaults
-         configure/RELEASE          TORNADO2 full path location
-
-       Host configuration
-       To configure each host system, you may override the default
-       definitions by adding a new file in the configure/os directory with
-       override definitions. The new file should have the same name as the
-       distribution file to be overridden except with CONFIG in the name
-       changed to CONFIG_SITE.
-
-         configure/os/CONFIG.<host>.<host>      Host build settings
-         configure/os/CONFIG.<host>.Common      Host common build settings
-
-       Target configuration
-       To configure each target system, you may override the default
-       definitions by adding a new file in the configure/os directory with
-       override definitions. The new file should have the same name as the
-       distribution file to be overridden except with CONFIG in the name
-       replaced by CONFIG_SITE. This step is necessary even if the host
-       system is the only target system.
-
-         configure/os/CONFIG.Common.<target>     Target common settings
-         configure/os/CONFIG.<host>.<target>     Host-target settings
-
-    Build EPICS base
-
-       After configuring the build you should be able to build EPICS base by
-       issuing the following commands in the distribution's root directory
-       (base):
-
-         gnumake clean uninstall
-         gnumake
-
-       The command "gnumake clean uninstall" will remove all files and
-       directories generated by a previous build. The command "gnumake" will
-       build and install everything for the configured host and targets.
-
-       It is recommended that you do a "gnumake clean uninstall" at the root
-       directory of an EPICS directory structure before each complete rebuild
-       to ensure that all components will be rebuilt.
-
-  Example application and extension
-
-     A perl tool, makeBaseApp.pl is included in the distribution file. This
-     script will create a sample application that can be built and then
-     executed to try out this release of base.
-
-     Instructions for building and executing the 3.15 example application can
-     be found in the section "Example Application" of Chapter 2, "Getting
-     Started", in the "IOC Application Developer's Guide" for this release.
-     The "Example IOC Application" section briefly explains how to create and
-     build an example application in a user created <top> directory. It also
-     explains how to run the example application on a vxWorks ioc or as a
-     process on the host system. By running the example application as a
-     host-based IOC, you will be able to quickly implement a complete EPICS
-     system and be able to run channel access clients on the host system.
-
-     A perl script, makeBaseExt.pl, is included in the distribution file.
-     This script will create a sample extension that can be built and
-     executed. The makeBaseApp.pl and makeBaseExt.pl scripts are installed
-     into the install location bin/<hostarch> directory during the base
-     build.
-
-  Multiple host platforms
-
-     You can build using a single EPICS directory structure on multiple host
-     systems and for multiple cross target systems. The intermediate and
-     binary files generated by the build will be created in separate
-     subdirectories and installed into the appropriate separate host/target
-     install directories. EPICS executables and perl scripts are installed
-     into the $(INSTALL_LOCATION)/bin/<arch> directories. Libraries are
-     installed into $(INSTALL_LOCATION)/lib/<arch>. The default definition
-     for $(INSTALL_LOCATION) is $(TOP) which is the root directory in the
-     distribution directory structure, base. Created object files are stored
-     in O.<arch> source subdirectories, This allows objects for multiple
-     cross target architectures to be maintained at the same time. To build
-     EPICS base for a specific host/target combination you must have the
-     proper host/target C/C++ cross compiler and target header files and the
-     base/configure/os directory must have the appropriate configure files.

-<H3><A NAME="0_0_1"> What is EPICS base?</A></H3>
-<BLOCKQUOTE>The Experimental Physics and Industrial Control Systems
- (EPICS) is an extensible set of software components and tools with
- which application developers can create a control system. This control
- system can be used to control accelerators, detectors, telescopes, or
- other scientific experimental equipment. EPICS base is the set of core
- software, i.e. the components of EPICS without which EPICS would not
- function. EPICS base allows an arbitrary number of target systems, IOCs
- (input/output controllers), and host systems, OPIs (operator
- interfaces) of various types.</BLOCKQUOTE>

-<BLOCKQUOTE> Please check the RELEASE_NOTES file in the distribution for
- description of changes and release migration details.</BLOCKQUOTE>

-
-<H3><A NAME="0_0_4"> Supported platforms</A></H3>
-
-<BLOCKQUOTE>The list of platforms supported by this version of EPICS base
- is given in the configure/CONFIG_SITE file. If you are trying to build
- EPICS Base on an unlisted host or for a different target machine you
- must have the proper host/target cross compiler and header files, and
- you will have to create and add the appropriate new configure files to
- the base/configure/os/directory. You can start by copying existing
- configuration files in the configure/os directory and then make changes
- for your new platforms.</BLOCKQUOTE>
-
-<H3><A NAME="0_0_5"> Supported compilers</A></H3>
-
-<BLOCKQUOTE>This version of EPICS base has been built and tested using the host
- vendor's C and C++ compilers, as well as the GNU gcc and g++ compilers. The GNU
- cross-compilers work for all cross-compiled targets. You may need the C and C++
- compilers to be in your search path to do EPICS builds; check the definitions
- of CC and CCC in base/configure/os/CONFIG.&lt;host&gt;.&lt;host&gt; if you have
- problems.</BLOCKQUOTE>
-
-<H3><A NAME="0_0_6"> Software requirements</A></H3>
-
-<BLOCKQUOTE><B>GNU make</B><BR>
- You must use GNU make, gnumake, for any EPICS builds. Set your path
- so that a gnumake version 3.81 or later is available.
-
-<P><B>Perl</B><BR>
- You must have Perl version 5.8.1 or later installed. The EPICS configuration
- files do not specify the perl full pathname, so the perl executable must
- be found through your normal search path.</P>
-
-<P><B>Unzip and tar (Winzip on WIN32 systems)</B><BR>
- You must have tools available to unzip and untar the EPICS base
- distribution file.</P>
-
-<P><B>Target systems</B><BR>
- EPICS supports IOCs running on embedded platforms such as VxWorks
- and RTEMS built using a cross-compiler, and also supports soft IOCs running
- as processes on the host platform.</P>
-
-<P><B>vxWorks</B><BR>
- You must have vxWorks 5.5.x or 6.x installed if any of your target systems are
- vxWorks systems; the C++ compiler for vxWorks 5.4 is now too old to support.
- The vxWorks installation provides the cross-compiler and header files needed to
- build for these targets. The absolute path to and the version number of the
- vxWorks installation must be set in the
- base/configure/os/CONFIG_SITE.Common.vxWorksCommon file or in one of its
- target-specific overrides.</P>
-
-<P>Consult the <a href="http://www.aps.anl.gov/epics/base/tornado.php">vxWorks
- 5.x</a> or <a href="http://www.aps.anl.gov/epics/base/vxWorks6.php">vxWorks
- 6.x</a> EPICS web pages about and the vxWorks documentation for information
- about configuring your vxWorks operating system for use with EPICS.</P>
-
-<P><B>RTEMS</B><BR>
- For RTEMS targets, you need RTEMS core and toolset version 4.9.2 or later.</P>
-
-<P><B>GNU readline or Tecla library</B><BR>
- GNU readline and Tecla libraries can be used by the IOC shell to
- provide command line editing and command line history recall and edit.
- GNU readline (or Tecla library) must be installed on your target system
- when COMMANDLINE_LIBRARY is set to READLINE (or TECLA) for that target.
- EPICS (EPICS shell) is the default specified in CONFIG_COMMON. A
- READLINE override is defined for linux-x86 in the EPICS distribution.
- Comment out COMMANDLINE_LIBRARY=READLINE in
- configure/os/CONFIG_SITE.Common.linux-x86 if readline is not installed
- on linux-x86. Command-line editing and history will then be those
- supplied by the os. On vxWorks the ledLib command-line input library is
- used instead.</P>

-<H3><A NAME="0_0_7"> Host system storage requirements</A></H3>
-
-<BLOCKQUOTE>The compressed tar file is approximately 1.6 MB in size. The
- distribution source tree takes up approximately 12 MB. Each host target will
- need around 40 MB for build files, and each cross-compiled target around 20
- MB.</BLOCKQUOTE>

+### <span id="0_0_1">What is EPICS base?</span>
+
+The Experimental Physics and Industrial Control Systems (EPICS) is an
+extensible set of software components and tools with which application
+developers can create a control system. This control system can be
+used to control accelerators, detectors, telescopes, or other
+scientific experimental equipment. EPICS base is the set of core
+software, i.e. the components of EPICS without which EPICS would not
+function. EPICS base allows an arbitrary number of target systems,
+IOCs (input/output controllers), and host systems, OPIs (operator
+interfaces) of various types.
+
+### <span id="0_0_2">What is new in this release?</span>
+
+Please check the `RELEASE_NOTES` file in the distribution for
+description of changes and release migration details.
+
+### <span id="0_0_3">Copyright</span>
+
+Please review the LICENSE file included in the distribution for legal
+terms of usage.
+
+### <span id="0_0_4">Supported platforms</span>
+
+The list of platforms supported by this version of EPICS base is given
+in the `configure/CONFIG_SITE` file. If you are trying to build EPICS
+Base on an unlisted host or for a different target machine you must
+have the proper host/target cross compiler and header files, and you
+will have to create and add the appropriate new configure files to the
+base/configure/os/directory. You can start by copying existing
+configuration files in the configure/os directory and then make
+changes for your new platforms.
+
+### <span id="0_0_5">Supported compilers</span>
+
+This version of EPICS base has been built and tested using the host
+vendor's C and C++ compilers, as well as the GNU gcc and g++
+compilers. The GNU cross-compilers work for all cross-compiled
+targets. You may need the C and C++ compilers to be in your search
+path to do EPICS builds; check the definitions of CC and CCC in
+`base/configure/os/CONFIG.<host>.<host>` if you have problems.
+
+### <span id="0_0_6">Software requirements</span>
+
+**GNU make**
+You must use GNU make, gnumake, for any EPICS builds. Set your path so
+that a gnumake version 3.81 or later is available.
+
+**Perl**
+You must have Perl version 5.8.1 or later installed. The EPICS
+configuration files do not specify the perl full pathname, so the perl
+executable must be found through your normal search path.
+
+**Unzip and tar (Winzip on WIN32 systems)**
+You must have tools available to unzip and untar the EPICS base
+distribution file.
+
+**Target systems**
+EPICS supports IOCs running on embedded platforms such as VxWorks and
+RTEMS built using a cross-compiler, and also supports soft IOCs
+running as processes on the host platform.
+
+**vxWorks**
+You must have vxWorks 5.5.x or 6.x installed if any of your target
+systems are vxWorks systems; the C++ compiler for vxWorks 5.4 is now
+too old to support. The vxWorks installation provides the
+cross-compiler and header files needed to build for these targets. The
+absolute path to and the version number of the vxWorks installation
+must be set in the `base/configure/os/CONFIG_SITE.Common.vxWorksCommon`
+file or in one of its target-specific overrides.
+
+Consult the [vxWorks 5.x](https://epics.anl.gov/base/tornado.php) or
+[vxWorks 6.x](https://epics.anl.gov/base/vxWorks6.php) EPICS web pages
+about and the vxWorks documentation for information about configuring
+your vxWorks operating system for use with EPICS.
+
+**RTEMS**
+For RTEMS targets, you need RTEMS core and toolset version 4.9.2 or
+later.
+
+**GNU readline or Tecla library**
+GNU readline and Tecla libraries can be used by the IOC shell to
+provide command line editing and command line history recall and edit.
+GNU readline (or Tecla library) must be installed on your target
+system when `COMMANDLINE_LIBRARY` is set to READLINE (or TECLA) for
+that target. EPICS (EPICS shell) is the default specified in
+`CONFIG_COMMON`. A READLINE override is defined for linux-x86 in the
+EPICS distribution. Comment out `COMMANDLINE_LIBRARY=READLINE` in
+`configure/os/CONFIG_SITE.Common.linux-x86` if readline is not
+installed on linux-x86. Command-line editing and history will then be
+those supplied by the os. On vxWorks the ledLib command-line input
+library is used instead.
+
+### <span id="0_0_7">Host system storage requirements</span>
+
+The compressed tar file is approximately 1.6 MB in size. The
+distribution source tree takes up approximately 12 MB. Each host
+target will need around 40 MB for build files, and each cross-compiled
+target around 20 MB.
+
+### <span id="0_0_8">Documentation</span>
+
+EPICS documentation is available through the [EPICS
+website](https://epics.anl.gov/) at Argonne.
+
+Release specific documentation can also be found in the
+base/documentation directory of the distribution.

+### <span id="0_0_12">Building EPICS base (Unix and Win32)</span>
+
+#### Unpack file
+
+Unzip and untar the distribution file. Use WinZip on Windows
+systems.
+
+#### Set environment variables
+
+Files in the base/startup directory have been provided to help set
+required path and other environment variables.
+
+* `EPICS_HOST_ARCH`
+Before you can build or use EPICS R3.15, the environment variable
+`EPICS_HOST_ARCH` must be defined. A perl script EpicsHostArch.pl in
+the base/startup directory has been provided to help set
+`EPICS_HOST_ARCH.` You should have `EPICS_HOST_ARCH` set to your
+host operating system followed by a dash and then your host
+architecture, e.g. solaris-sparc. If you are not using the OS
+vendor's c/c++ compiler for host builds, you will need another dash
+followed by the alternate compiler name (e.g. "-gnu" for GNU c/c++
+compilers on a solaris host or "-mingw" for MinGW c/c++ compilers on
+a WIN32 host). See `configure/CONFIG_SITE` for a list of supported
+`EPICS_HOST_ARCH` values.
+
+* `PERLLIB`
+On WIN32, some versions of Perl require that the environment
+variable PERLLIB be set to &lt;perl directory location>.
+
+* `PATH`
+As already mentioned, you must have the perl executable and you may
+need C and C++ compilers in your search path. For building base you
+also must have echo in your search path. For Unix host builds you
+also need ln, cpp, cp, rm, mv, and mkdir in your search path and
+/bin/chmod must exist. On some Unix systems you may also need ar and
+ranlib in your path, and the C compiler may require as and ld in
+your path. On solaris systems you need uname in your path.
+
+* `LD_LIBRARY_PATH`
+R3.15 shared libraries and executables normally contain the full
+path to any libraries they require. However, if you move the EPICS
+files or directories from their build-time location then in order
+for the shared libraries to be found at runtime `LD_LIBRARY_PATH`
+must include the full pathname to
+`$(INSTALL_LOCATION)/lib/$(EPICS_HOST_ARCH)` when invoking
+executables, or some equivalent OS-specific mechanism (such as
+/etc/ld.so.conf on Linux) must be used. Shared libraries are now
+built by default on all Unix type hosts.
+
+#### Do site-specific build configuration
+
+**Site configuration**
+To configure EPICS, you may want to modify the default definitions
+in the following files:
+
+```
+        configure/CONFIG_SITE      Build choices. Specify target archs.
+        configure/CONFIG_SITE_ENV  Environment variable defaults
+        configure/RELEASE          TORNADO2 full path location
+```
+
+**Host configuration**
+To configure each host system, you may override the default
+definitions by adding a new file in the configure/os directory with
+override definitions. The new file should have the same name as the
+distribution file to be overridden except with CONFIG in the name
+changed to `CONFIG_SITE`.
+
+```
+        configure/os/CONFIG.<host>.<host>      Host build settings
+        configure/os/CONFIG.<host>.Common      Host common build settings
+```
+
+**Target configuration**
+To configure each target system, you may override the default
+definitions by adding a new file in the configure/os directory with
+override definitions. The new file should have the same name as the
+distribution file to be overridden except with CONFIG in the name
+replaced by `CONFIG_SITE`. This step is necessary even if the host
+system is the only target system.
+
+```
+        configure/os/CONFIG.Common.<target>     Target common settings
+        configure/os/CONFIG.<host>.<target>     Host-target settings
+```
+
+#### Build EPICS base
+
+After configuring the build you should be able to build EPICS base
+by issuing the following commands in the distribution's root
+directory (base):
+
+```
+        gnumake clean uninstall
+        gnumake
+```
+
+The command "gnumake clean uninstall" will remove all files and
+directories generated by a previous build. The command "gnumake"
+will build and install everything for the configured host and
+targets.
+
+It is recommended that you do a "gnumake clean uninstall" at the
+root directory of an EPICS directory structure before each complete
+rebuild to ensure that all components will be rebuilt.
+
+### <span id="0_0_13">Example application and extension</span>
+
+A perl tool, makeBaseApp.pl is included in the distribution file. This
+script will create a sample application that can be built and then
+executed to try out this release of base.
+
+Instructions for building and executing the 3.15 example application
+can be found in the section "Example Application" of Chapter 2,
+"Getting Started", in the "IOC Application Developer's Guide" for this
+release. The "Example IOC Application" section briefly explains how to
+create and build an example application in a user created &lt;top>
+directory. It also explains how to run the example application on a
+vxWorks ioc or as a process on the host system. By running the example
+application as a host-based IOC, you will be able to quickly implement
+a complete EPICS system and be able to run channel access clients on
+the host system.
+
+A perl script, makeBaseExt.pl, is included in the distribution file.
+This script will create a sample extension that can be built and
+executed. The makeBaseApp.pl and makeBaseExt.pl scripts are installed
+into the install location `bin/<hostarch>` directory during the base

+### <span id="0_0_14">Multiple host platforms</span>
+
+You can build using a single EPICS directory structure on multiple
+host systems and for multiple cross target systems. The intermediate
+and binary files generated by the build will be created in separate
+subdirectories and installed into the appropriate separate host/target
+install directories. EPICS executables and perl scripts are installed
+into the `$(INSTALL_LOCATION)/bin/<arch>` directories. Libraries are
+installed into $`(INSTALL_LOCATION)/lib/<arch>`. The default
+definition for `$(INSTALL_LOCATION)` is `$(TOP)` which is the root
+directory in the distribution directory structure, base. Created
+object files are stored in `O.<arch>` source subdirectories, This
+allows objects for multiple cross target architectures to be
+maintained at the same time. To build EPICS base for a specific
+host/target combination you must have the proper host/target C/C++
+cross compiler and target header files and the base/configure/os
+directory must have the appropriate configure files.

+characters:
+

+=head3 Scan Fields
+
+These fields contain information related to how and when a record processes. A
+few records have unique fields that also affect how they process. These
+fields, if any, will be listed and explained in the section for each record.
+
+The B<SCAN> field specifies the scanning period for periodic record scans or the
+scan type for non-periodic record scans.  The default set of values for SCAN can
+be found in L<menuScan.dbd|menuScan>.
+
+The choices provided by this menu are:
+
+=over
+
+=item *
+
+C<Passive> for the record scan to be triggered by other records or Channel
+Access
+
+=item *
+
+C<Event> for event-driven scan
+
+=item *
+
+C<I/O Intr> for interrupt-driven scan
+
+=item *
+
+A set of periodic scan intervals
+
+=back
+
+Additional periodic scan rates may be defined for individual IOCs by making a
+local copy of menuScan.dbd and adding more choices as required. Scan rates
+should normally be defined in order, with the fastest rates appearing first.
+Scan periods may now be specified in seconds, minutes, hours or Hertz/Hz, and
+plural time units will also be accepted (seconds are used if no unit is
+mentioned in the choice string). For example the rates given below are all
+valid:
+
+ 1 hour
+ 0.5 hours
+ 15 minutes
+ 3 seconds
+ 1 second
+ 2 Hertz
+
+The B<PINI> field specifies record processing at initialization. If it is set
+to YES during database configuration, the record is processed once at IOC
+initialization (before the normal scan tasks are started).
+
+The B<PHAS> field orders the records within a specific SCAN group. This is not
+meaningful for passive records. All records of a specified phase are processed
+before those with higher phase number. Whenever possible it is better to use
+linked passive records to enforce the order of processing rather than a phase
+number.
+
+The B<EVNT> field specifies an event number. This event number is used if the
+SCAN field is set to C<Event>. All records with scan type C<Event> and the
+same EVNT value will be processed when a call to post_event for EVNT is made.
+The call to post_event is: post_event(short event_number).
+
+The B<PRIO> field specifies the scheduling priority for processing records
+with SCAN=C<I/O Event> and asynchronous record completion tasks.
+
+The B<DISV> field specifies a "disable value". Record processing is
+immediately terminated if the value of this field is equal to the value of the
+DISA field, i.e. the record is disabled. Note that field values of a record
+can be changed by database  put or Channel Access, even if a record is
+disabled.
+
+The B<DISA> field contains the value that is compared with DISV to determine
+if the record is disabled. The value of the DISA field is obtained via SDIS if
+SDIS is a database or channel access link. If SDIS is not a database or
+channel access link, then DISA can be set via dbPutField or dbPutLink.
+
+If the B<PROC> field of a record is written to, the record is processed.
+
+The B<DISS> field defines the record's "disable severity". If this field is
+not NO_ALARM and the record is disabled, the record will be put into alarm
+with this severity and a status of DISABLE_ALARM.
+
+The B<LSET> field contains the lock set to which this record belongs. All
+records linked in any way via input, output, or forward database links belong
+to the same lock set. Lock sets are determined at IOC initialization time, and
+are updated whenever a database link is added, removed or altered.
+
+The B<LCNT> field counts the number of times dbProcess finds the record active
+during successive scans, i.e. PACT is TRUE. If dbProcess finds the record
+active MAX_LOCK times (currently set to 10) it raises a SCAN_ALARM.
+
+The B<PACT> field is TRUE while the record is being processed. For
+asynchronous records PACT can be TRUE from the time record processing is
+started until the asynchronous completion occurs. As long as PACT is TRUE,
+dbProcess will not call the record processing routine. See Application
+Developers Guide for details on usage of PACT.
+
+The B<FLNK> field is a database link to another record (the "target" record).
+Processing a record with a specified FLNK field will force processing of the
+target record, provided the target record's SCAN field is set to C<Passive>.
+
+The B<SPVT> field is for internal use by the scanning system.

+=head3 Alarm Fields
+
+These fields indicate the status and severity of alarms, or else determine the
+how and when alarms are triggered. Of course, many records have alarm-related
+fields not common to all records. These fields are listed and explained in the
+appropriate section on each record.
+
+The B<STAT> field contains the current alarm status.
+
+The B<SEVR> field contains the current alarm severity.
+
+These two fields are seen outside database access. The B<NSTA> and B<NSEV>
+fields are used by  the database access, record support, and device support
+routines to set new alarm status and severity values. Whenever any software
+component discovers an alarm condition, it uses the following macro function:
+recGblSetSevr(precord,new_status,new_severity) This ensures that the current
+alarm severity is set equal to the highest outstanding alarm. The file alarm.h
+defines all allowed alarm status and severity values.
+
+The B<ACKS> field contains the highest unacknowledged alarm severity.
+
+The B<ACKT> field specifies if it is necessary to acknowledge transient
+alarms.
+
+The B<UDF> indicates if the record's value is B<U>nB<D>eB<F>ined. Typically
+this is caused by a failure in device support, the fact that the record has
+never been processed, or that the VAL field currently contains a NaN (not a
+number). UDF is initialized to TRUE at IOC initialization. Record and device
+support routines which write to the VAL field are responsible for setting UDF.

+
+=head3 Debugging Fields
+
+The B<TPRO> field is used for trace processing. If this field is non-zero a
+message is printed whenever this record is processed, and when any other
+record in the same lock-set is processed by a database link from this record.
+
+The B<BKPT> field indicates if there is a breakpoint set at this record. This
+supports setting a debug breakpoint in the record processing. STEP through
+database processing can be supported using this.
+
+=fields TPRO, BKPT
+
+
+=head3 Miscellaneous Fields
+
+The B<ASG> field contains a character string value defining the access
+security group for this record. If left empty, the record is placed in group
+DEFAULT.
+
+The B<ASP> field is a field for private use of the access security system.
+
+The B<DISP> field controls dbPutFields to this record which are normally
+issued by channel access. If the field is set to TRUE all dbPutFields
+directed to this record are ignored except to the field DISP itself.
+
+The B<DTYP> field specifies the device type for the record. Each record type
+has its own set of device support routines which are specified in
+devSup.ASCII. If a record type does not have any associated device support,
+DTYP and DSET are meaningless.
+
+The B<MLOK> field contains the monitor lock. The lock used by the monitor
+routines when the monitor list is being used. The list is locked whenever
+monitors are being scheduled, invoked, or when monitors are being added to or
+removed from the list. This field is accessed only by the dbEvent routines.
+
+The B<MLIS> field is the head of the list of monitors connected to this
+record. Each record support module is responsible for triggering monitors for
+any fields that change as a result of record processing. Monitors are present
+if mlis count is greater than zero. The call to trigger monitors is:
+db_post_event(precord,&data,mask), where "mask" is some combination of
+DBE_ALARM, DBE_VALUE, and DBE_LOG.
+
+The B<PPN> field contains the address of a putNotify callback.
+
+The B<PPNR> field contains the next record for PutNotify.
+
+The B<PUTF> field is set to TRUE if dbPutField caused the current record
+processing.
+
+The B<RDES> field contains the address of dbRecordType
+
+The B<RPRO> field specifies a reprocessing of the record when current
+processing completes.
+
+The B<TIME> field contains the time when this record was last processed in
+standard format.
+
+The B<TSE> field indicates the mechanism to use to get the time stamp. '0' -
+call get time as before '-1' - call the time stamp driver and use the best
+source available. '-2' - the device support provides the time stamp from the
+hardware. Values between 1-255 request the time of the last occurance of a
+generalTime event.
+
+The B<TSEL> field contains an input link for obtaining the time stamp. If this
+link references the .TIME field of a record then the time stamp of the
+referenced record becomes the time stamp for this record as well. In this
+case, an internal flag is set and ".TIME" is then overwritten by ".VAL". If
+any other field is referenced, the field value is read and stored in the .TSE
+field which is then used to acquire a timestamp.

+=head1 Fields Common to Input Record Types
+
+This section describes fields that are found in many input record types.
+These fields usually have the same meaning whenever they are used.
+
+See also L<Fields Common to All Record Types|dbCommonRecord> and L<Fields Common
+to Output Record Types|dbCommonOutput>.
+
+=head3 Input and Value Fields
+
+The B<INP> field specifies an input link. It is used by the device support
+routines to obtain input. For soft analog records it can be a constant, a
+database link, or a channel access link.
+
+The B<DTYP> field specifies the name of the device support module that will
+input values. Each record type has its own set of device support routines. If
+a record type does not have any associated device support, DTYP is
+meaningless.
+
+The B<RVAL> field contains - whenever possible - the raw data value exactly as
+it is obtained from the hardware or from the associated device driver and
+before it undergoes any conversions. The Soft Channel device support module
+reads values directly into VAL, bypassing this field.
+
+The B<VAL> field contains the record's final value, after any needed
+conversions have been performed.
+
+=head3 Device Input
+
+A device input routine normally returns one of the following values to its
+associated record support routine:
+
+=over
+
+=item *
+
+0: Success and convert. The input value is in RVAL. The record support module
+will compute VAL from RVAL.
+
+=item *
+
+2: Success, but don't convert. The device support module can specify this
+value if it does not want any conversions. It might do this for two reasons:
+
+=over
+
+=item *
+
+A hardware error is detected (in this case, it should also raise an alarm
+condition).
+
+=item *
+
+The device support routine reads values directly into the VAL field and then
+sets UDF to FALSE. For some record types the device support routine may have to
+do other record-specific processing as well such as applying a smoothing filter
+to the engineering units value.
+
+=back
+
+=back
+
+=head3 Device Support for Soft Records
+
+In most cases, two soft output device support modules are provided: Soft Channel
+and Raw Soft Channel. Both allow INP to be a constant, a database link, or a
+channel access link. The Soft Channel device support module reads input directly
+into the VAL field and specifies that no value conversion should be performed.
+This allows the record to store values in the data type of its VAL field. Note
+that for Soft Channel input, the RVAL field is not used. The Raw Soft Channel
+support module reads input into RVAL and indicates that any specified unit
+conversions be performed.
+
+The device support read routine normally calls C<dbGetLink()> which
+fetches a value from the link.
+
+If a value was returned by the link the UDF field is set to FALSE. The device
+support read routine normally returns the status from C<dbGetLink()>.
+
+
+=head3 Input Simulation Fields
+
+The B<SIMM> field controls simulation mode. It has either the value YES or NO.
+By setting this field to YES, the record can be switched into simulation mode
+of operation. While in simulation mode, input will be obtained from SIOL
+instead of INP.
+
+Ths B<SIML> specifies the simulation mode location. This field can be a
+constant, a database link, or a channel access link. If SIML is a database or
+channel access link, then SIMM is read from SIML. If SIML is a constant link
+then SIMM is initialized with the constant value but can be changed via
+dbPuts.
+
+Ths B<SVAL> field contains the simulation value. This is the record's input
+value, in engineering units, when the record is switched into simulation mode,
+i.e. when SIMM is set to YES.
+
+The B<SIOL> field is a link that can be used to fetch the simulation value. The
+link can be a constant, a database link, or a channel access link. If SIOL is a
+database or channel access link, then SVAL is read from SIOL. If SIOL is a
+constant link then SVAL is initialized with the constant value but can be
+changed via dbPuts.
+
+The B<SIMS> field specifies the simulation mode alarm severity. When this
+field is set to a value other than NO_ALARM and the record is in simulation
+mode, it will be put into alarm with this severity and a status of SIMM.
+
+=head3 Simulation Mode for Input Records
+
+An input record can be switched into simulation mode of operation by setting
+the value of SIMM to YES or RAW. During simulation, the record will be put
+into alarm with a severity of SIMS and a status of SIMM_ALARM. While in
+simulation mode, input values will be read from SIOL instead of INP:
+
+           -- (SIMM = NO?) INP (if supported and directed by device support, -> RVAL -- convert -> VAL), (else -> VAL)
+         /
+
+ SIML -> SIMM
+
+         \
+          -- (SIMM = YES?) SIOL -> SVAL -> VAL
+           \
+             -- (SIMM = RAW?) SIOL -> SVAL -> RVAL -- convert -> VAL
+
+A record can be switched into simulation mode of operation by setting the
+value of SIMM to YES. During simulation, the record will be put into alarm
+with a severity of SIMS and a status of SIMM_ALARM. While in simulation mode,
+input values, in engineering units, will be obtained from SIOL instead of INP.
+Also, while the record is in simulation mode, there will be no raw value
+conversion and no calls to device support when the record is processed.
+
+Normally input records contain a private readValue() routine which performs
+the following steps:
+
+=over
+
+=item *
+
+If PACT is TRUE, the device support read routine is called, status is set to
+its return code, and readValue returns.
+
+=item *
+
+Call C<dbGetLink()> to get a new value for SIMM from SIML.
+
+=item *
+
+Check value of SIMM.
+
+=item *
+
+If SIMM is NO, then call the device support read routine, set status to its
+return code, and return.
+
+=item *
+
+If SIMM is YES, then call C<dbGetLink()> to read the input value from SIOL
+into SVAL. If success, then set VAL to SVAL and UDF to FALSE and set status to
+2 (don't convert) if input record supports conversion. If SIMS is greater than
+zero, set alarm status to SIMM and severity to SIMS. Set status to the return
+code from recGblGetLinkValue and return.
+
+=item *
+
+If SIMM is RAW, then call C<dbGetLink()> to read the input value from SIOL
+into SVAL. If success, then set RVAL to SVAL and UDF to FALSE and set status
+to 0 (convert) if input record supports conversion. If SIMS is greater than
+zero, set alarm status to SIMM and severity to SIMS. Set status to the return
+code from recGblGetLinkValue and return.
+
+=item *
+
+If SIMM is not YES, NO or RAW, a SOFT alarm with a severity of INVALID is
+raised, and return status is set to -1.

+=head1 Fields Common to Output Record Types
+
+This section describes fields that are found in many output record types.
+These fields usually have the same meaning whenever they are used.
+
+See also L<Fields Common to All Record Types|dbCommonRecord> and L<Fields Common to
+Input Records|dbCommonInput>.
+
+=head3 Output and Value Fields
+
+The B<OUT> field specifies an output link. It is used by the device support
+routines to decide where to send output. For soft records, it can be a
+constant, a database link, or a channel access link. If the link is a
+constant, the result is no output.
+
+The B<DTYP> field specifies the name of the device support module that will
+input values. Each record type has its own set of device support routines. If
+a record type does not have any associated device support, DTYP is
+meaningless.
+
+The B<VAL> field contains the desired value before any conversions to raw
+output have been performed.
+
+The B<OVAL> field is used to decide when to invoke monitors. Archive and value
+change monitors are invoked if OVAL is not equal to VAL. If a record type
+needs to make adjustments, OVAL is used to enforce the maximum rate of change
+limit before converting the desired value to a raw value.
+
+The B<RVAL> field contains - whenever possible -  the actual value sent to the
+hardware itself or to the associated device driver.
+
+The B<RBV> field contains - whenever possible - the actual read back value
+obtained from the hardware itself or from the associated device driver.
+
+
+=head3 Device Support for Soft Records
+
+Normally two soft output device support modules are provided, Soft Channel and
+and Raw Soft Channel. Both write a value through the output link OUT.
+The Soft Channel module writes output from the value associated with OVAL or
+VAL (if OVAL does not exist). The Raw Soft Channel support module writes the
+value associated with the RVAL field after conversion has been performed.
+
+The device support write routine normally calls C<dbPutLink()> which writes a
+value through the OUT link, and returns the status from that call.
+
+
+=head3 Input and Mode Select Fields
+
+The B<DOL> field is a link from which the desired output value can be fetched.
+DOL can be a constant, a database link, or a channel access link. If DOL is a
+database or channel access link and OMSL is closed_loop, then VAL is obtained
+from DOL.
+
+The B<OMSL> field selects the output mode. This field has either the value
+C<supervisory> or C<closed_loop>. DOL is used to fetch VAL only if OMSL has the
+value C<closed_loop>. By setting this field a record can be switched between
+supervisory and closed loop mode of operation. While in closed loop mode, the
+VAL field cannot be set via dbPuts.
+
+=head3 Output Mode Selection
+
+The fields DOL and OMSL are used to allow the output record to be part of a
+closed loop control algorithm. OMSL is meaningful only if DOL refers to a
+database or channel access link. It can have the values C<supervisory> or
+C<closed_loop>. If the mode is C<supervisory>, then nothing is done to VAL. If
+the mode is C<closed_loop> and the record type does not contain an OIF field,
+then each time the record is processed, VAL is set equal to the value obtained
+from the location referenced by DOL. If the mode is C<closed_loop> in record
+types with an OIF field and OIF is Full, VAL is set equal to the value obtained
+from the location referenced by DOL; if OIF is Incremental VAL is incremented by
+the value obtained from DOL.
+
+=head3 Invalid Output Action Fields
+
+The B<IVOA> field specifies the output action for the case that the record is
+put into an INVALID alarm severity. IVOA can be one of the following actions:
+
+=over
+
+=item *
+
+C<Continue normally>
+
+=item *
+
+C<Don't drive outputs>
+
+=item *
+
+C<Set output to IVOV>
+
+=back
+
+The B<IVOV> field contains the value for the IVOA action C<Set output to IVOV>
+in engineering units. If a new severity has been set to INVALID  and IVOA is
+C<Set output to IVOV>, then VAL is set to IVOV and converted to RVAL before
+device support is called.
+
+=head3 Invalid Alarm Output Action
+
+Whenever an output record is put into INVALID alarm severity, IVOA specifies
+an action to take. The record support process routine for each output record
+contains code which performs the following steps.
+
+=over
+
+=item *
+
+If new severity is less than INVALID, then call C<writeValue()>:
+
+=item *
+
+Else do the following:
+
+=over
+
+=item *
+
+If IVOA is C<Continue normally> then call C<writeValue()>.
+
+=item *
+
+If IVOA is C<Don't drive outputs> then do not write output.
+
+=item *
+
+If IVOA is C<Set output to IVOV> then set VAL to IVOV, call C<convert()> if
+necessary, and then call C<writeValue()>.
+
+=item *
+
+If IVOA not one of the above, an error message is generated.
+
+=back
+
+=back
+
+
+=head3 Simulation Fields
+
+The B<SIMM> field controls simulation mode. It has either the value YES or NO.
+By setting this field to YES, the record can be switched into simulation mode
+of operation. While in simulation mode, output will be forwarded through SIOL
+instead of OUT.
+
+Ths B<SIML> specifies the simulation mode location. This field can be a
+constant, a database link, or a channel access link. If SIML is a database or
+channel access link, then SIMM is read from SIML. If SIML is a constant link
+then SIMM is initialized with the constant value but can be changed via
+dbPuts.
+
+The B<SIOL> field is a link that the output value is written to when the record
+is in simulation mode.
+
+The B<SIMS> field specifies the simulation mode alarm severity. When this
+field is set to a value other than NO_ALARM and the record is in simulation
+mode, it will be put into alarm with this severity and a status of SIMM.
+
+=head3 Simulation Mode
+
+An output record can be switched into simulation mode of operation by setting
+the value of SIMM to YES. During simulation, the record will be put into alarm
+with a severity of SIMS and a status of SIMM_ALARM. While in simulation mode,
+output values, in engineering units, will be written to SIOL instead of OUT.
+However, the output values are never converted. Also, while the record is in
+simulation mode, there will be no calls to device support during record
+processing.
+
+Normally output records contain a private C<writeValue()> routine which performs
+the following steps:
+
+=over
+
+=item *
+
+If PACT is TRUE, the device support write routine is called, status is set to
+its return code, and readValue returns.
+
+=item *
+
+Call C<dbGetLink()> to get a new value for SIMM if SIML is a DB_LINK or a
+CA_LINK.
+
+=item *
+
+Check value of SIMM.
+
+=item *
+
+If SIMM is NO, then call the device support write routine, set status to its
+return code, and return.
+
+=item *
+
+If SIMM is YES, then call C<dbPutLink()> to write the output value from VAL or
+OVAL to SIOL. Set alarm status to SIMM and severity to SIMS, if SIMS is
+greater than zero. Set status to the return code from C<dbPutLink()> and
+return.
+
+=item *
+
+If SIMM not one of the above, a SOFT alarm with a severity of INVALID is
+raised, and return status is set to -1.
