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.
