manually via modem commands. Read Section 3
for a summary description of the modem command
set before manually accessing the modem. You
may want to read the software manual first,
however, as the software may already provide a
user friendly method of accessing the functions you
need (i.e. dialing or answering calls).
2.9 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 Command Mode until you dial a number and
establish aconnection. 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.
