Hi,

Recently, I posted a question about me having a problem with my 1200 baud
modem (the 'dialing tones' were just a bit of noise, while it worked fine
at my friend's place with his PS/2). This is still unsolved, but I have an
alternative in pulse dialing (AT DP instead of AT DT).

Now, if I try calling a BBS with Procomm 2.4.2, the BBS picks up the phone,
sounds some beeps at different frequencies (for baud rate determination?),
and then...hangs up, while my modem still waits for a connection.
Obviously, it does not respond to the signals from the BBS.

Apart from this, when I type 'AT', I get nothing, whereas I should get
'OK'. And of course, tone dialing (AT DT) is still not working (I'll try
setting the tone duration longer).

These problems occur with any combination of Procomm 2.4.2 or Windows 3.1
Terminal, and a 386 clone or a Bull Micral 35F. But they do not occur with
Procomm 2.3 on a PS/2... Furthermore, I've tries 3 different cables and
both COM ports, but I still get no positive result. BTW. The modem is a
Repko M2000 TRIO.

Does anybody know what is going on / what I am doing wrong?
  Thanks in advance,
    Marcel.
