AT Command List

AT commands are issued from an asynchronous DTE, such as a PC, and control the modem’s operation and software configuration. AT commands are only applicable when the DTE Dialer Type configuration option is set for AT. (Refer to the &Mn and &Qn commands.)

Table 14-2 lists all AT commands supported by the 391x Series modem. The first column lists the AT command. The second column defines and lists all possible values for that command. The Async Dial factory default is listed in bold. The third column lists the key sequence used to enter the equivalent DCP command. Use this to reference commands in Chapters 4 through 12 if further description is necessary.

AT Command Format

AT commands are entered in Command mode using the following format:

TYPE: ATXn

Where: X is the AT command and n is the specific value for that command.

PRESS: Enter

In Table 14-2, the value for X is listed in the AT Command column and the value for n is listed in the Description column.
