AT Command Reference

AT Commands Overview

Command Alphabet

The ASCII character set is the alphabet used for the AT command set. Only the low order seven bits of each character are considered significant.

Case Sensitivity

Although AT commands are specified in uppercase throughout this Integrator’s Reference Manual, both uppercase and lowercase are valid. The modem does not distinguish between uppercase and lowercase letters.

Command Line Format

AT command lines are made up of three parts: the prefix, the body, and the termination character.

The command line prefix consists of the letters AT. The command line prefix is followed by the body, which consists of one or more AT commands. Command syntax for each specific AT command within the body is as specified in this document, for example, E or $QCSTATUS.

Space characters can be used freely within the body for formatting purposes. Command lines are terminated with the termination character specified by S-register S3 (see Command Line Termination Character (S3) on page 6-25). The default value of S3 is the carriage return character <CR> (ASCII value of 13 decimal).

You can use an alternate command line prefix, which causes the previously entered command line (body and terminator) to be executed. This command line prefix consists of the letters A/.

Note No terminator is required after entering the / character to begin command line execution.
