Section Three - AT Command Set

3.1 Executing 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 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, and 57600 bps. Make sure your COM port baud rate setting 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 com- mands. 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.
