Modem Setup: Suggested Initialize Command


(Contents)(Previous)(Next)

If you can't find your modem in the Modem Selection window, we suggest you initialize your modem with this (the spaces between commands are optional and make no difference other than readability):

AT &C1 &D2 E1 Q0 V1 X4

These commands tell a Hayes-compatible modem to:

1. &C1 (Ampersand C one) Sets the modem to use the Data Carrier Detect (DCD) signal to tell PC Access when it is connected to a service.

2. &D2 (Ampersand D two) Allow PC Access to hang up the connection by clearing (dropping) the Data Terminal Ready (DTR) signal.

3. E1 (E one) Echo, to the computer, all characters the computer sends to the modem while the modem is processing commands.

4. Q0 (Q zero) Send PC Access the results of each modem command.

5. V1 (V one) Send the results in verbose form, i.e., as words.

6. X4 Send extended result information to PC Access.

You can usually add a M0 (M zero) command in the initialization if you want the modem to be silent when it dials. This is sometimes desirable in offices where the modem's sounds might be distracting to others.
