I don't know about the printer driver, it may add garbage,
but I believe there's a program on your system for typing
AT commands to the modem. Terminal or hyperterminal
or some such in older systems...
Forgot to add this in the original. From the beginning I was able to send AT commands directly to the modem using a copy of ProComm Plus. It has the full set of AT commands (afaik).

A side note, When having the generic text printer on com3, same as the modem, when hitting the "Print Test Page" feature, you can actually hear the modem pick up the line (ATH1), and do a dtmf of "4", and then hangup (ATH0).


The serial modem will be waiting for me Monday. I am going to see if I can capture the data across the serial and see what protocols are at play.
