In most cases, you will not need to type AT commands manually.
However, there might be some occasions when you will need to do so.
This chapter describes AT commands for data mode. Fax and voice
commands are taken care of by application software.
The format for entering AT commands is:
ATXn
where
X
is the AT command, and
n
is the specific value for that
command. After you type in the command press
Enter
.
Any command issued is acknowledged with a response in either text or
numeric values known as result codes.
All commands and command-values accepted by the modem are
described in this section; any entry other than those listed results in an
error.

The escape sequence allows the modem to exit data mode
and enter on-line command mode. While in on-line
command mode, you can communicate directly to your
modem using AT commands. Once you finish, you can
return to data mode using the ATO command.
A pause, the length of which is set by Escape Guard Time
(S12), must be completed after an escape sequence is
entered, This pause prevents the modem from interpreting
the escape sequence as data.
The value of the escape sequence character may be
changed using register S2.
