![Page 27 of 187TECHNICAL MANUALTelit GM862 PCSTri Band GPRS Data Terminal System Rev.12 AT CommandThe Telit GM862-PCS module can be driven via the serial interface using the standard ATcommands1. The Telit GM862-PCS module is compliant with:1. Hayes standard AT command set, in order to maintain the compatibility with existing SWprograms.2. ETSI GSM 07.07 specific AT command and PCS specific commands.3. ETSI GSM 07.05 specific AT commands for SMS (Short Message Service) and CBS (CellBroadcast Service)4. FAX Class 1 compatible commandsMoreover the Telit GM862-PCS module supports also Telit proprietary AT commands for specialpurposes.In the following the dedicated description of how to use the AT commands with the Telit GM862-PCS module.2.1 DefinitionsThe following syntactical definitions apply:<CR> Carriage return character, is the command line and result code terminator character, whichvalue, in decimal ASCII between 0 and 255,is specified within parameter S3.The default value is 13.<LF> Linefeed character, is the character recognised as line feed character. Its value, in decimalASCII between 0 and 255, is specified within parameter S4. The default value is 10.The line feed character is output after carriage return character if verbose result codes are used (V1option used ) otherwise, if numeric format result codes are used (V0 option used) it will not appearin the result codes.<...> Name enclosed in angle brackets is a syntactical element. They do not appear in thecommand line.[...] Optional subparameter of a command or an optional part of TA information responseis enclosed in square brackets. Brackets themselves do not appear in the command line. Whensubparameter is not given in AT commands which have a read command, new value equals to itsprevious value. In AT commands which do not store the values of any of their subparameters, andso have not a read command, which are called action type commands, action should be done on thebasis of the recommended default setting of the subparameter. 1 The AT is an ATTENTION command and is used as a prefix to other parameters in a string. TheAT command combined with other parameters can be set up in the communications package ortyped in manually as a command line instruction.](https://usermanual.wiki/Telit-Communications-S-p-A/GM862P/User-Guide-381259-Page-35.png)
