AT Command Set 1.3 Conventions Throughout the document, the GSM engines are referred to as ME (Mobile Equipment), MS (Mobile Station), TA (Terminal Adapter), DCE (Data Communication Equipment) or facsimile DCE (FAX mo- dem, 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 control- ling devi

AT Command Set 1.4.2 Combining AT commands on the same command line You may enter several AT commands on the same line. This eliminates the need to type the "AT" or "at" prefix before each command. Instead, it is only needed once at the beginning of the command line. Use a semicolon as command delimiter. The command line buffer accepts a maximum of 391 characters. If this number is exceeded none of the commands will be executed and TA returns ERROR. The table below lists

AT Command Set 1.5 Supported character sets The ME supports two character sets: GSM 03.38 (7 bit, also referred to as SMS alphabet) and UCS2 (16 bit, refer to ISO/IEC 10646). See Chapter 4.44 for information about selecting the character set. Character tables are provided in Chapter 9.5. Due to the constraints described below it is recommended to prefer the USC2 alphabet in any external application. If the GSM alphabet is selected all characters sent over the serial line a

AT Command Set 1.6 Flow control Flow control is essential to prevent loss of data or avoid errors when, in a data or fax call, the sending device is transferring data faster than the receiving side is ready to accept. When the receiving buffer reaches its capacity, the receiving device should be capable to cause the sending device to pause un- til it catches up. There are basically two approaches to regulate data flow: software flow control and hardware flow control. The Hig
