1.2. AT Command Set

Remote-control operation of the GSM mobile telephone runs via a serial interface,where AT+C commands according to GSM 07.07 and GSM 07.05 as well as severalmanufacturer-specific AT commands are available. These commands are describedin more detail on the following pages.

The commands are entered by way of the operating functions of the respective baseunit. This converts the operating functions to AT commands so that the mobile phonecan execute the required action. The following should be noted:

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 (= 0x0D). The input of a command is acknowledged by thedisplay of OK or ERROR. A command currently in process is interrupted byeach additional character entered. This means that you should not enter the nextcommand until you have received the acknowledgment; otherwise the currentcommand is interrupted.

The commands supported are listed in the following tables:

1.2 .1 . Hayes-Standard Com m ands

The Hayes-standard commands correspond to the commands of AT Hayes-compatible modems.

Command Function

A/ Repeat last command

AT... Prefix for all other commands

ATA Accept call

ATD; Dial the dialing string with the voice utilityValid dial modifiers: T (tone dialing), P (pulse dialing) is ignored.The character ; is important, for this tells the phone that the callshould be set up with the voice utility. Otherwise an attempt ismade to set up a data call, which the phone immediatelyacknowledges with ERROR.

ATD>; Dial the telephone number from the current telephone book locationnumber The telephone book is selected with the command at+cpbs

1.3. AT Commands and Responses According to GSM 07.07 and GSM 07.05

According to GSM, it is possible to execute an AT command in various forms.

Test command AT+CXXX=? The telephone responds by sending the list ofparameters and value ranges; these can be set using

the affiliated Write command or by means of internalprocesses.

Read command AT+CXXX? This command tells you the current value setting ofthe parameter(s).

Write command AT+CXXX= This command is used to set parameters that can beset.

Execute command AT+CXXX The Execute command reads non-settableparameters which are influenced by internal processesin the telephone.
