[comp.dcom.modems] Ven-Tel 212 hangups on bin. transfers

I access the United States through a satellite net which terminates in Santa
Clara California. From there I dialout to the world through a Ven-Tel 212
Plus -II modem Version 2.20.............
  Most of the time it works very well, but whenever I or anyone else attempt to
download xmodemed files (or any error checking program) from ANY system the
modem hangs up. The time varies from day-to-day, but it always seems to hang up
It is a 1200 baud modem. One time I tried fooling it by logging in at 300 baud
and trying the upload. It worked 1 time - then the machine got smart the next .
  My me and huing up again!
    I don't have the books on the modem, so I need to know how to re-program to
This is very mdem's registers to disable the timeout....
Dores anyone have any knowledge of these machines?
  There is one other possibility . .. the Tymnet engine that we use could be do
in it.
Any help would be appreciated.

Tymnet will not pass all 256 binary characters transparently unless you
tell it to, and if you do not, xmodem will not work except occasionally.
Talk to Tymnet and they can set up the port to pass all 8 bit characters
transparently.
