AT command set

(ATtention command set) A series of machine instructions used to activate features on an analog modem. Developed by Hayes Microcomputer Products and officially known as the Hayes Standard AT Command Set, it is used entirely or partially by most every modem manufacturer. AT is a mnemonic code for ATtention, which is the prefix that initiates each command to the modem. See Hayes Smartmodem.
