UUCP Script Problems

[CAT-TALK Maint. Account]

I'm using the following script to call one of my UUCP feeder
sites. The idea is that it should continue to retry the call
until the call completes successfully. (There is a problem with
noisy phone lines and the antiquated Merit Network which cause
calls to fail in midstream):


# !/bin/csh
#
/usr/lib/uucp/uucico -r1 -Ssharkey
while ($status != 0)
   sleep 300
   /usr/lib/uucp/uuxqt
   /usr/lib/uucp/uucico -r1 -Ssharkey 
end

The problem is, that this will go at most twice through the loop and
then will exit, regardless of wether uucico failed or succeeded on the
last try. I think the problem is that uucico returns different return
codes for different types of errors. Could someone send me a list of
return codes for uucico.

I'm running SCO Xenix 2.3.2 (HDB UUCP).  Thanks
