Normally: speed is not really important. You can use any speed. I believe if
you set the highest, the modem would automatically fall back to its highest
speed. I am not sure about this though. The other parameters: 8N1. I.e. 8
databits, No Parity, 1 stopbit. This is quite normal.
> 2. How to configure the modem (ATwxyz, etc)
That depends on the modem. However, almost all modems are Hayes compatible.
This means the commands are standardized. Check any Hayes commandlist on the
internet.
> 3. How to make the modem dial and establish a connection
See 2. The hayes command is ATDTnumber for Tone Dialling.

Just check what you recieve from the other side. But on a dial up program
for Linux I saw once, I just had to type this in myself. After that, I got
PPP.

In DOS terms: just put your strings to the COM device and it arrives at the
modem which will send it to the server.

Probably: see 2. But Erik Maas should be able to tell you all about this. He
wrote Erix, one of the best communication programs for MSX.

Also a Hayes command, called Hang up. I don't know the commandletter by
heart though.

Maybe.

Sorry, I don't have mine anymore... But nowadays it should be REALLY simple
and cheap to get one. 14k4 e.g. Bought mine a couple of years ago for only
NLG 75, which is 75/2.20371 Euros.
> Thanks for any help,
I hope this helps.
Best regards,
Manuel
