P Driver support for CAEN board 1932

Now, we have working version, which is generic for all known boards. But, because there is one software PRIMARY channel which sets limits for all channels, the interface is kind of fuzzy. Later we probably should separate 1932 board interface. The PRIMARY channel is not configured in $APP/hvca/db/<whatever>.db .So, shift takers will be obscured from internals of this board. But, experts should be aware of internals CAEN A1932. They have to connect using telnet like:

telnet hvpcal 1527

Then enter username and password of mainframe and change PRIMARY channel settings.

• Upload this version into CVS.
• Then upload sy527 version for vxWorks.
• Then upload merged sy1527-sy527 version into CVS.

X Software IOC startup configurations

The software IOC-es are running on:

clonpc1 - gamma and tpe profilers
clonpc2 - HV of beam line devices (hvDvcs CAEN MF)
clonpc3 - test setups for CAEN HV MF-es (hvPCal and hvTest)

Startup directories now are $IOC/`hostname -s`. These files are used:

/usr/local/clas/release/current/R3.14.8.2/EPICS/ioc/clonpc1:
 envPaths
 softioc.pipe
 startup.all
/usr/local/clas/release/current/R3.14.8.2/EPICS/ioc/clonpc2:
 envPaths
 softioc.pipe
 startup.all
/usr/local/clas/release/current/R3.14.8.2/EPICS/ioc/clonpc3:
 envPaths  
 softioc.pipe
 startup.all

Startup script is /etc/init.d/softioc and it is different for each compter. Basically, because software IOC requires active STDIN (otherwise it dies), we make FIFO or named pipe, and using cat we are connecting it to the STDIN of software IOC. Besides, it is nicer than "sleep 1000d", it allows to send commands to software IOC (only once, because EOF or some signal is sent, which means exit to software IOC). This allows to avoid kill process, which leaves active the semaphore. To protect softioc.pipe files they made with read-only permissions.

O classc2 recovery

We suspect something wrong with scalers.
