AT stands for ATtention. It is a way of interacting with the modem. Every command line starts with "AT" or "at". They are called AT commands because the characters AT must precede each command to get the ATtention of the modem

As already told by wmz, you can find more about it here: AT Commands - WikiPedia

Command: AT Attention Code

Values: n/a

Description: The attention code precedes all command lines except A/, A: and escape sequences.

If you mean modem commands - if memory serves - this comes from first letters of ATtention [which modem should pay] to command

I do not have any sources, although Wiki seems to agree: http://en.wikipedia.org/wiki/Hayes_command_set

The following text lists part of the Hayes command set (also called the AT commands: "AT" meaning attention).
