Need Help w/UUCP Problem

[Marc Snyder]

Hello all,
	Lately I have been having a problem with one of my SCO Xenix
machines.  The machine is a Compaq 386/20 Deskpro, running SCO Xenix
2.2.6, and I am using a Telebit+ on /dev/tty1A.  The system has been
running perfectly for long time.  Recently, while dialing out to two
other machines (one running 386/ix, and the other running 4.2 BSD Unix I
believe -- they are both using telebits) a strange thing happens.  If I
do a uucico -r1 -x9 -Ssitename I get the following results:  my machine
dials sitename, logs in, the uucp conversation begins, and then I get:

*** TOP *** - role=1,

And that's the end of the conversation.  My system keeps the phone line
open, and the LCK files remain in /usr/spool/uucp.  To further complicate
the problem, it doesn't happen all the time, and I can't seem to figure
out under what situations it does happen.  Also, my LOGFILE looks like:

marcs sitename (3/8-15:01) SUCCEEDED (call to sitename)
marcs sitename (3/8-15:01) OK (startup)

If I don't kill the uucico processes, and then remove the LCK files, the
phone line is useless.  I have checked the modem's roms and registers,
and the cable.  I have also rebooted the machine to make sure that the
serial port is being reset properly.  Does anyone out there have any
ideas as to what could be causing this problem.  Thanks in advance for
your help!
