AT Commands for Modem Initialization
In most cases, the default modem initialization commands are acceptable. For
when changes are necessary, this section provides a brief introduction to the
AT (ATtention code) commands that are used to control the modem’s
operation. The command format is ATXn, where X is the command and n is
the numeric value for the command. If the value is 0 (zero), it can be omitted
from the command. For example, AT&W is the same as AT&W0. The following
table defines the most-commonly-used commands: ATA, ATD, ATH, ATM,
ATV, ATZ, AT&F, and AT&W.
