Realtime Status Exchange: Modifications
***************************************

In order to simplify the realtime status exchange between the laser stations we
have prepared a C program to be run under UNIX or on a Windows PC that directly
connects to port 7810 on our system, sends a line of text and receives the
current merged status messages.

The program is called as follows:

  eurostat aiuli3.unibe.ch 7810 'n' [<textfile] [>statusfile]

The program reads from the standard input the locally generated status line and
writes the received status to the standard output.

The standard input (i.e., the local status line) can of course be piped into
the program, the received merged status on the standard output can be piped into
some display program if necessary.

'n' is the number of receive cycles to be run, a zero means an infinite number.
Usually 'n' should be set to 1 and the program should be called in a loop every
15 to 30 seconds.

The program can also be used to just receive the compiled status file
indefinitely by omitting any standard input and by setting 'n' to zero.

In order to recover if the server on our end is stopped temporarily or if some
other error happens, you should embed the call to the program into a loop in a
script or batch file in any case.

The C source (eurostat.c) and the PC executable (eurostat.exe_dos) can be
found on ftp.unibe.ch/aiub/slr.

I would like to thank Martin Ploner of our institute for the generation of the
C program.

Please contact me if you have any problems or suggestions.

Best regards,

Werner
