- Fixed a bug fix with Fixed motor in TAS code

- Made AMOR write HDF-5 data in chunks
- Added  driver for a PSI-DSP magnet controller as used at SLS
- Added code for directly accessing RS232 controllers connected to a
  terminal server, thereby bypassing the SerPortServer
- A rounding problem in the PSD histogram memory was resolved.

+<p>
+The PSI-DSP magnet controller has been developed by the PSI
+electronics  group, most notably by Lukas Tanner, for the
+SLS. However, these controllers are now being used at SINQ as
+well. This controller has a binary command protocoll and thus the send
+command does not work for it. In order to handle this protocoll SICS 
+has to bypass the usual SerPortServer mechanism for communicating with 
+serial devices
+and to connect to the terminal server directly. This also implies one
+gotcha: <b>
+The PSI-DSP works only at specially configured terminal server
+ports</b>.The terminal server
+port to which the PSI-DSP is connected <b>MUST</b> be configured to:
+115200 baud, 8 data bits, 1 stop bit, odd parity. In general a system
+manager is required to do this. The PSI-DSP also requires a null-modem
+connector between the box and the terminal server. Once these hurdles
+have been mastered, the PSI-DSP can be configured into SICS with the
+command:
+<BLOCKQUOTE>
+evfactory new name psi-dsp terminalservername port
+</BLOCKQUOTE>
+with name being the name of the magnet in SICS, terminalservername the
+name of the terminal server, for example psts224 and port being the
+address of the binary port on the terminal server. This is usually
+the serial port number at the terminal server plus 3000. An example:
+<BLOCKQUOTE>
+evfactory new maggi psi-dsp psts224 3016
+</BLOCKQUOTE>
+configures a magnet named maggi which is connectd to port 16 at the
+terminal server psts224. maggi can now be read and driven like any
+other environment device.
