Hayes AT Commands

The Hayes AT (ATtention) commands are a standard set of instructions for controlling a modem. They were developed in the mid 1980’s by Hayes Micro Computers, hence the name Hayes. Until then modems had been dumb, meaning that they had no memory, and could not be programmed. With the advent of the codes modems became far more functional. The Hayes command set is now regarded as a standard for modem control.
