Wish I could be more help on this one...  All I can tell you here is that
your UNIX-PC must be sitting there like a terminal with a modem on it, ready
to answer the phone when it rings, and go into a data mode..

The only other problem I've had with "ct" is it appears as though you can NOT
run a uugetty on the "out-bound" port of the computer that is CALLING you.
The outbound port should be just that, outbound only..  Running a uugetty on
this port will do STRANGE things, like drop the session shortly after you
connect and hit a few returns..

With no getty, your phone should ring, you answer, the modems connect, hit
return a few times and you should see a login message!
