(works for most U.S. Robotics modems)
If it is not working for you, you can edit the
modem.ini file as needed. Table 22 contains
reference information on these commands. The “AT” at the beginning gets the modem’s
“ATtention”, then commands follow in uppercase with no spaces between them. Look in
your modem user manual for more information.

Connections
Local Connect
If you have the local connect option, connect one end of our cable to the serial port of your
PC. Connect the other end to the serial connector in the terminal.
Phone Line Connect
Be sure that you have the PC modem connected to one (outgoing) phone line, and the
terminal connected to a separate (incoming) phone line: the modem in the Model 2100/
2200 must see ringing to answer.
In other words, you cannot just hook the modems directly together. If you happen to have
a telephone tester or telephone line simulator that can provide ringing, you can use it
instead of going through the central office.
Be sure you are plugged into the LINE jack of the modem card in slot 2 or 3 of the paging
terminal, not the PHONE jack. We usually cover up the PHONE jack with a label to help
prevent this problem.
On the modem for your PC, similarly check that you are using the LINE jack, and not the
PHONE jack.

&C1 CD (Carrier Detect) active, not fixed or ignored.
&D3 DTR response is to hang up and reset the modem.
