AT Command Set Remote control operation of the GSM mobile telephone runs via a serial interface (data cable of infrared connection), where AT+C commands according to ETSI GSM 07.07 and GSM 07.05 specification as well as several manufacturer specific AT commands are available. These commands are described in more detail later on.

The modem guideline V.25ter applies to the sequence of the interface commands. According to this guideline, commands should begin with the character string ”AT” and end with ”” (= 0×0D). The input of a command is acknowledged by the display of ”OK” or ”ERROR”. A command currently in process is interrupted by each additional character entered. This means that you should not enter the next command until you have received the acknowledgment; otherwise the current command is interrupted.
