Terminal Adapter AT Commands

One of the ways you can communicate with and configure your terminal

adapter (TA) is to use AT commands. AT commands are so-called because,

with only a few exceptions, each command string begins with the characters

. Using AT commands, you can read and set parameters and perform

actions such as dialing.

Entering AT Commands

You can send AT commands to the TA by typing them on the keyboard, by

typing them in the terminal window of a data communications program such

as HyperTerminal, or indirectly by configuring your data communications

program.
Enter AT commands in the following format:

AT <command string> <cr>

The

characters

cause the TA to interpret the following string of

characters as a command. The command string consists of one or more

commands. The carriage return character, <cr>, sends the command string

to the TA. If you are entering a command string in your communication

programs terminal window, insert the carriage return character by pressing
