Subject: HDB UUCP fails on AT&T 3B2/310

Has anyone else experienced problems with HoneyDanBer UUCP running on
an AT&T 3B2/310, Version 3.0 of the operating system?  I have noticed
the following quite frequently:

	1.	Sending compressed binaries (16-bit compression) with
		Penril modem 8216 from an AT&T 3B2 to another AT&T 3B2
		long distance, I receive the imfamous:

			CONVERSATION FAILED 
			IN SEND/SLAVE MODE INPUT FAILURE

	2.	Uncompress binary, send either full size or use the "pack"
		utility sends fine.  It is always the same program
		that bombs.

We had to remove our compress-batched news feed because of this problem.
I have heard this is a problem with noise on the line, but I seriously
doubt it.  I watched the UUCP in -x9 debug mode, and it bombs at one
particular point (same point) each time.  Is there a "sequence of 
characters" that is bombing my modem to command mode?  (ie. like the 
"+++" sequence on a Hayes compatible modem?)  NOTE: I have the command
feature turned off on these modems.

When this happens the modem sends-receives-sends fine, but at the "critical"
point, it stops... pauses for about 1 minute, then bursts of SEND and RECEIVE
data at the same time, soon after leading to the failure.

Any ideas?  I don't like sending 300K binaries, when I can send 150K compressed
ones! Especially LONG DISTANCE!

						Thanks,
