1.3 ConventionsThroughout the document, the GSM engines are referred to as ME (Mobile Equipment), MS (MobileStation), TA (Terminal Adapter), DCE (Data Communication Equipment) or facsimile DCE (FAX modem,FAX board). When the Siemens product names are required to distinguish the two models,MC35 is short for the engine type and MC35T for the terminal.To control your GSM engine you can simply send AT Commands via its serial interface. The controllingdevice at the other end of the serial line is referred to as TE (Terminal Equipment), DTE (DataTerminal Equipment) or plainly ´the application´ (probably running on an embedded system).1.4 AT command syntaxThe "AT" or "at" prefix must be set at the beginning of each command line. To terminate a commandline enter .Commands are usually followed by a response that includes “”.Throughout this document, only the responses are presented, are omitted intentionally.Table 1: Types of AT commands and responsesTest command AT+CXXX=? The mobile equipment returns the list of parameters andvalue ranges set with the corresponding Write commandor by internal processes.Read command AT+CXXX? This command returns the currently set value of the parameteror parametersWrite command AT+CXXX= This command sets user-definable parameter values.Execution command AT+CXXX The execution command reads non-variable parametersaffected by internal processes in the GSM engine.1.4.1 Using parameters• Default parameters are underlined throughout this document.• Optional parameters are enclosed in square brackets. If optional parameters are omitted, the currentsettings are used until you change them.• Optional parameters or subparamters can be omitted unless they are followed by other parameters.If you want to omit a parameter in the middle of a string it must be replaced by a comma. Example:AT+CPBW=,,, writes a phonebook entry to the first free memory location.AT+CPBW=,,, writes a phonebook entry to the memory locationspecified by .• When the parameter is a character string, e.g. or , the string must be enclosed inquotation marks, e.g. "Charlie Brown" or "+49030xxxx". Symbols within quotation marks will berecognized as strings.• All spaces will be ignored when using strings without quotaton marks.• It is possible to omit the leading zeros of strings which represent numbers.• In case of using V.25ter commands without giving an optional parameter, its value is assumed tobe 0.Page 13 of 207
