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
AT. 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 AT characters cause the TA to interpret the following string of

commands. The carriage return character, <cr>, sends the command string
to the TA. If you are entering a command string in your communication
program’s terminal window, insert the carriage return character by pressing
