provide a user friendly method of accessing the functions you
need (i.e. dialing or answering calls).
2.8 Where To Go From Here
You should familiarize yourself with the functions
available from the included software by reading its manual.
You will be accessing most, if not all, of the modem's
functions from this software. You may also use any other
commercially available communication software with the
modem. Read Section 3 ONLY if you are interested in
accessing the modem manually, and not through the included
software. Section 4 and 5 contain reference material, and can
be skipped. If you have difficulties getting your modem to
work, read Section 6, Troubleshooting to find answers to
commonly asked questions and problems.
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.
