AT Command Set 1 Introduction This document provides the AT Command Set for the following Siemens GSM engines: • TC35 Module • TC37 Module • TC35 Terminal The AT commands detailed in this document are supported by all three products. Where differences occur, they are noted in the chapter that refers to the command. In this version, the only exception is the AT^SSYNC command that offers various modes depending on the model (see Chapter 6.34). 1.
PAGE 9
AT Command Set 1.2 Restrictions If autobauding is active, the multiplex mode (see +CMUX, pg. 67) can´t be activated (and if multiplex mode has been entered, AT+IPR= is not possible). When the serial interface is in multiplex mode (see +CMUX, pg. 67), data calls are only possible on logical channel 1. Due to this restriction, AT commands have a different behaviour on channels 2+3 compared to channel 1. Some commands are not available, some other commands have a different response.
PAGE 10
AT Command Set 1.3 Supported character sets The ME uses 2 character sets: GSM 03.38 (7 bit, see character tables in annex 7.10 „Alphabet tables“, pg. 144) and UCS2 (16 Bit, refer ISO/IEC 10646). Also refer to subclause „AT+CSCS Set TE character set", pg. 83. With the intention of using an ASCII terminal to enter characters which are coded differently in ASCII and GSM (e.g. Ä, Ö, Ü), these characters have to be entered via escape sequences.
PAGE 11
AT Command Set 2 Standard V.25ter AT Commands These AT Commands are related to ITU-T (International Telecommunication Union, Telecommunication sector) V.25ter document. The TC35 Module, the TC37 Module and the TC35 Terminal support the registers S0-S29. You can change S0,S3,S4,S5,S6,S7,S8,S10,S18 by using the appropriate ATSn commands. All the other registers are read-only and for internal usage only! 2.

PAGE 33
AT Command Set previous bit rate. Because in autobaud mode the ME doesn´t know which bit rate is to be used after power-on. For this reason the unsolicited result code “SYSSTART” cannot be sent. Therefore it is recommended to first send an At Command string (see pg. 10) to the ME to let the autobaud mechanism determine the bit rate used by the TE. If this command switches from a bit rate that can´t be detected by the autobaud mechanism (e.g.
PAGE 34
AT Command Set 3 AT Commands for FAX The following commands can be used for FAX transmission. If the ME is acting as a Fax-Modem to a PC-based application (e.g. „WinFax“) it is necessary to select the proper Service Class (Fax Class) provided by the ME. The ME reports its Service Class capabilities, both the current setting and the range of services avaible. This is provided by the AT+FCLASS command (see pg. 36).
PAGE 35
AT Command Set 3.2 AT+FBADMUL Error Threshold Multiplier Read command AT+FBADMUL ? This command defines the “Copy-Quality-OK” multiplier. The number of lines received with a bad pixel count is multiplied by this number. If the result exceeds the total number of lines on the page the error rate is considered too high. A threshold multiplier value of 20 corresponds to a 5% error rate. A value of 0 implies that error checking is not present or disabled.
