Section Three - AT Command Set

3.1 Commands

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

connection. Commands may be sent to your modem from

a PC running communication software or any other

terminal devices.

Your modem is capable of data communication at

rates of: 300, 1200, 2400, 4800, 9600, 14400, 19200,

28800, 38400, 57600, and 115200 bps. Make sure your

COM port baud rate in your communications software is

set to one of the above speeds.

3.2 Command Structure

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 commands. If you omit a parameter from a

command that requires one, it is just like specifying a

parameter of 0. Example:

ATH [ENTER]

This command causes your modem to hang up.
