	I had one failure in capability of an Avatex 1200 bps modem that
I'd like to share with the net.  The Avatex was unable to complete a text
file transfer from the ST to a VAX, using Kermit.  When the Avatex was
replaced with a Hayes Smartmodem 1200, the file uploaded with no problems.

	For almost 2 weeks, the Avatex worked fine for interactive modem
communications.  It's a minor annoyance not to have a speaker to monitor
for busy signals (although a jack for a spare telephone is provided).
The Avatex runs slightly warmer than the Hayes, but not excessively so.
I have line noise problems when dialing into work with the Hayes; the
Avatex had the same behavior.  When dialing BBs with no line noise (based
on use of the Hayes), the Avatex also performed flawlessly.

	So, no problems: Hayes performance at 1200 bps with an $89 price!
That is, until I tried a text file upload from home to the VAX at work
(520 ST, 1 megabyte memory, PC InterComm terminal program at home).  Using
Kermit, the file transfer started, but then just stopped (in one case,
after uploading 2 blocks, in another, after 7 blocks).  It's as if Kermit
was waiting for some kind of handshake from the Avatex, but never got it.
Making no other changes, I switched from the Avatex to the Hayes, and the
entire text file uploaded correctly.

	Anyone else seen this behavior with an Avatex modem?

	By the way, the new model Avatex (100 % Hayes compatible, approx.
$130) is available.  I *THINK* it has a built-in speaker.  I wonder what
else it does to justify an almost-50% increase in price!
