Chapter 1 – AT Commands

Multi-Tech Systems, Inc. AT Commands for the MT5634 Family of Products (S000272J) 4

Chapter 1 - AT Commands

Introduction

The AT commands are used to control the operation of your modem. They are called AT commands because the

characters AT must precede each command to get the ATtention of the modem.

AT commands can be issued only when the modem is in command mode or online command mode. The modem

is in command mode whenever it is not connected to another modem. The modem is in data mode whenever it is

connected to another modem and ready to exchange data. Online command mode is a temporary state in which

you can issue commands to the modem while connected to another modem. To put the modem into online

command mode from data mode, you must issue an escape sequence (+++) followed immediately by the AT

characters and the command, e.g., +++ to hang up the modem. To return to data mode from online command

mode, you must issue the command ATO.

To send AT commands to the modem you must use a communications program, such as the HyperTerminal

applet in Windows 98/95 and NT 4.0, or some other available terminal program. You can issue commands to the

modem either directly, by typing them in the terminal window of the communications program, or indirectly, by

configuring the operating system or communications program to send the commands automatically. Fortunately,

communications programs make daily operation of modems effortless by hiding the commands from the user.

Most users, therefore, need to use AT commands only when reconfiguring the modem; e.g., to turn autoanswer

on or off.

The format for entering an AT command is ATXn, where Xis the command and nis the specific value for the

command, sometimes called the command parameter. The value is always a number. If the value is zero, you

can omit it from the command; thus, AT&W is equivalent to AT&W0. Most commands have a default value,

which is the value that is set at the factory.

You must press ENTER (depending on the terminal program it could be some other key) to send the command

to the modem. Any time the modem receives a command, it sends a response known as a result code. The

most common result codes are OK, ERROR, and the CONNECT messages that the modem sends to the

computer when it is connecting to another modem.

You can issue several commands in one line, in what is called a command string. The command string begins

with AT and ends when you press ENTER. Spaces to separate the commands are optional; the command

interpreter ignores them. The most familiar command string is the initialization string, which is used to

configure the modem when it is turned on or reset, or when your communications software calls another modem.
