AT Commands

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.

+++ Escape sequence

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

A/ Repeat last command

This command repeats the last command string entered. Do not

precede this command with an AT prefix or conclude it by pressing

Enter.
