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.
