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.
