Commands are accepted by the modem while it is in

Command Mode. Your modem is automatically in Com-
mand Mode until you dial a number and establish a connec-
tion. Commands may be sent to your modem from a PC
running communication software or any other terminal de-
vices.

Your modem is capable of data communication at rates

of:  300, 1200, 2400, 4800, 9600, 14400, 19200, 38400,
57600, and 115200 bps. Make sure your COM port baud rate
settings in your communications software is set to one of the
above speeds.

All commands sent to the modem must begin with AT

and end with ENTER.  All commands may be typed in either
upper or lower case, but not mixed. To make the command
line more readable, spaces may be inserted between com-
mands. If you omit a parameter from a command that
requires one, it is just like specifying a parameter of 0.
Example:

This command causes your modem to hang up.

In the following listings, all default settings are printed
