AT Commands

AT commands are used to control MODEMs. AT is the abbreviation for

Attention. These commands come from Hayes commands that were used by

the Hayes smart modems. The Hayes commands started with AT to indicate

the attention from the MODEM. The dial up and wireless MODEMs (devices

that involve machine to machine communication) need AT commands to

interact with a computer. These include the Hayes command set as a subset,

along with other extended AT commands.
