Section Three - AT Command Set

3.1Executing Commands

Commands are accepted by the modem while it is in Command Mode. Your modem is automatically in Command 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 settings in your communications software is set to one of the above speeds.

3.2Command 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.
