|
|
|
|
<h2>vxWorks TIMEZONE pentium</h2>
|
|
|
|
<p>If the name of the timezone has more than a few characters a crash can
|
|
occur on pentium vxWorks iocs. See ansiTime in the vxWorks reference manual
|
|
for details about TIMEZONE.</p>
|
|
|
|
<h2>epicsReadLine</h2>
|
|
|
|
<p>src/libCom/osi/os/default/epicsReadline.c used a char variable to hold the
|
|
return value from getc(), and compared this against EOF. getc() returns int
|
|
not char because ANSI C allows char to be unsigned if the architecture finds
|
|
that easier, thus EOF can never be stored in a char on a PowerPC CPU. char
|
|
should be changed to int or signed char.</p>
|
|
|
|
<h2>RTEMS and NTP</h2>
|
|
|
|
<p>The RTEMS startup routine waits until a time synchronization packet is
|
|
received from an NTP server. This causes the RTEMS intialization to loop
|
|
endlessly if there is no NTP server on the network.
|
|
This problem has been fixed in the CVS version by allowing the initialization
|
|
to time out after a minute or so and to set the IOC time to January 1, 2001.</p>
