When the Siemens product names are required to distinguish the two models, TC35i is short for the engine type and TC35iT for the terminal. To control your GSM engine you can simply send AT Commands via its serial interface. The controlling device at the other end of the serial line is referred to as TE (Terminal Equipment), DTE (Data Terminal Equipment) or plainly 'the application' (probably running on an embedded system). All abbreviations and acronyms used throughout this document are based on the GSM specifications. For definitions please refer to TR 100 350 V7.0.0 (1999-08), (GSM 01.04, version 7.0.0 release 1998). 1.3.1 Quick reference table Each AT command description includes a table similar to the example shown below. The table is intended as a quick reference to indicate the following functions: PIN: Is the AT command PIN protected? % Yes ! No Usage is dependent on conditions specified for the command, or not all command types are PIN protected (for example write command PIN protected, read command not). Note: The table provided in the Chapter Available AT Commands and Dependency on SIM PIN uses the same symbols. ASC0: Is the AT command supported on the physical serial interface ASC0? % Yes ! No Note: In the case of TC35i only "Yes" applies. MUXn: Is the AT command usable on the Multiplexer channels MUX1, MUX2, MUX3? % Yes ! No AT command is usable, but under the restrictions specified in the chapter related to the command. Note: The columns MUX1, MUX2 and MUX3 are relevant only when the GSM engine operates in Multiplexer mode, that is, when the physical serial interface is partitioned into 3 virtual channels by using the Multiplexer protocol. Usage is the same on ASC0 and MUX1.

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 the AT commands you cannot enter together with other commands on the same line. Otherwise, the responses may not be in the expected order.

TC35i_ATC_V02.07 Confidential / Released Page 17 of 439 1/30/04 TC35i AT Command Set 1.5 Supported character sets s mobile 1.5 Supported character sets The ME supports two character sets: GSM 03.38 (7 bit, also referred to as GSM alphabet or SMS alphabet) and UCS2 (16 bit, refer to ISO/IEC 10646). See AT+CSCS for information about selecting the character set. Character tables can be found below. Explanation of terms * IRA IRA means that one byte is displayed as two characters in hexadecimal format. for example, the byte 0x36 (decimal 54) is displayed as "36" (two chars). Escape sequences The escape sequence used within a text coded in the GSM default alphabet (0x1B) must be correctly interpreted by the TE, both for character input and output. To the module, an escape sequence appears like any other byte received or sent. TE TE is the terminal equipment that uses the GSM default alphabet as its character set. MS Hyperterminal (often used with the module) is an ANSI / ASCII terminal that does not support the GSM default alphabet. Data Coding Scheme The Data Coding Scheme (dcs) is part of a short message and is saved on the SIM. When writing a short message to the SIM in textmode, the dcs stored with AT+CSMP is used. TE Character Set The currently used TE character set is selected with AT+CSCS. * * * * The behavior when encountering characters, that are not valid characters of the supported alphabets, is undefined. 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 are in the range from 0 ... 127. CAUTION: GSM alphabet is not ASCII alphabet! Several problems resulting from the use of the GSM alphabet: * * "@" character with GSM alphabet value 0 is not printable by an ASCII terminal program (e.g. Microsoft(c) Hyperterminal(R)). "@" character with GSM alphabet value of binary 0 will terminate any C string! This is because the 0 is defined as C string end tag. Therefore, the GSM Null character may cause problems on application level when using a 'C'-function as "strlen()". This can be avoided if it is represented by an escape sequence as shown in the table below. By the way, this may be the reason why even network providers often replace "@"with "@=*" in their SIM application. Other characters of the GSM alphabet are misinterpreted by an ASCII terminal program. For example, GSM "o" (as in "Borse") is assumed to be "|" in ASCII, thus resulting in "B|rse". This is because both alphabets mean different characters with values hex. 7C or 00 and so on. In addition, decimal 17 and 19 which are used as XON/XOFF control characters when software flow control is activated, are interpreted as normal characters in the GSM alphabet. * * When you write characters differently coded in ASCII and GSM (e.g. A, O, U), you need to enter escape sequences. Such a character is translated into the corresponding GSM character value and, when output later, the GSM character value can be presented. Any ASCII terminal then will show wrong responses.

In this case, an escape sequence will be handled as normal characters. The most common workaround to this problem is to write a script which includes a decimal code instead of an escape sequence. This way you can write, for example, short messages which may contain differently coded characters.

On receipt of this code, a receiving entity shall display a space until another extension table is defined. 2) This code represents the EURO currency symbol. The code value is the one used for the character 'e'. Therefore a receiving entity which is incapable of displaying the EURO currency symbol will display the character 'e' instead. 3) This code is defined as a Page Break character and may be used for example in compressed CBS messages. Any mobile which does not understand the 7 bit default alphabet table extension mechanism will treat this character as Line Feed.

When the receiving buffer reaches its capacity, the receiving device should be capable to cause the sending device to pause until it catches up. There are basically two approaches to regulate data flow: software flow control and hardware flow control. The High Watermark of the input / output buffer should be set to approximately 60% of the total buffer size. The Low Watermark is recommended to be about 30%. The data flow should be stopped when the capacity rises close to the High Watermark and resumed when it drops below the Low Watermark. The time required to cause stop and go results in a hysteresis between the High and Low Watermarks. In Multiplex mode, it is recommended to use hardware flow control. 1.6.1 Software flow control (XON/OFF flow control) Software flow control sends different characters to stop (XOFF, decimal 19) and resume (XON, decimal 17) data flow. The only advantage of software flow control is that three wires would be sufficient on the serial interface. 1.6.2 Hardware flow control (RTS/CTS flow control) Hardware flow control sets or resets the RTS/CTS wires. This approach is faster and more reliable, and therefore, the better choice. When the High Watermark is reached, CTS is set inactive until the transfer from the buffer has completed. When the Low Watermark is passed, CTS goes active once again. To achieve smooth data flow, ensure that the RTS/CTS lines are present on your application platform. The application should include options to enable RTS/CTS handshake with the GSM engine. This needs to be done with the AT command AT\Q3 - it is not sufficient to set RTS/CTS handshake in the used Terminal program only. The default setting of the GSM engine is AT\Q0 (no flow control) which must be altered to AT\Q3 (RTS/CTS hardware handshake on). The setting is stored volatile and must be restored each time after the GSM engine was switched off. AT\Q has no read command. To verify the current setting of AT\Q, simply check the settings of the active profile with AT&V. Often, fax programs run an intialization procedure when started up. The intialization commonly includes enabling RTS/CTS hardware handshake, eliminating the need to set AT\Q3 once again. However, before setting up a CSD call, you are advised to check that RTS/CTS handshake is set. RTS/CTS hardware handshake must also be set if you want to take advantage of the CYCLIC SLEEP modes. For further details refer to AT+CFUN. Note: After deactivating the RTS line, the ME may still send up to 264 bytes (worst case). This can be easily handled if the buffer of the host application is sufficiently sized, and if a hysteresis is implemented in its Rx buffer. For host applications that are required to handle a large amount of data at high speed, a total buffer capacity of 512 bytes is recommended. TC35i_ATC_V02.07 Confidential / Released Page 25 of 439 1/30/04 TC35i AT Command Set 1.7 Unsolicited Result Code Presentation s mobile 1.7 Unsolicited Result Code Presentation URC stands for Unsolicited Result Code and is a report message issued by the ME without being requested by the TE, i.e. a URC is issued automatically when a certain event occurs. Hence, a URC is not issued as part of the response related to an executed AT command. Typical events leading to URCs are incoming calls ("RING"), received SMs, changing temperature, status of the battery etc. A summary of all URCs is given in chapter Summary of Unsolicited Result Codes (URC). To announce a pending URC transmission the ME will do the following: * * Activates its Ring line (logic "1") for one second, i.e. the line changes to physical "Low" level. This allows the TE to enter power saving mode until ME related events request service. If the AT command interface is busy a "BREAK" will be sent immediately but the URC will not be issued until the line is free. This may happen if the URC is pending while an AT command is being processed, i.e. during the time from sending the first character "A" of an AT command by the TE until the ME has responded with "OK" or "ERROR", or during a data call. Please note that AT command settings may be necessary to enable in-band signaling, e.g. refer to AT+CMER or AT+CNMI. It is strongly recommended to use the multiplex mode to map logical communication channels onto the serial line of the TC35i, for details refer to [4] and AT command AT+CMUX. Doing so it is possible to use one channel to still process URCs while having a data call active on another. For most of these messages, the ME needs to be configured whether or not to send an URC. Depending on the AT command, the URC presentation mode can be saved to the user defined profile (see AT&W), or needs to be activated every time you reboot the ME. Several URCs are not user definable, such as "^SYSSTART", "^SYSSTART 1.7.1 Communication between Customer Application and TC35i Leaving hardware flow control unconsidered the Customer Application (TE) is coupled with the TC35i (ME) via a receive and a transmit line. Since both lines are driven by independent devices collisions may (and will) happen, i.e. while the TE issues an AT command the TC35i starts sending an URC. This probably will lead to the TE's misinterpretation of the URC being part of the AT command's response. To avoid this conflict the following measures must be taken: * If an AT command is finished (with "OK" or "ERROR") the TE shall always wait at least 100 milliseconds before sending the next one. This gives the TC35i the opportunity to transmit pending URCs and get necessary service. Note that some AT commands may require more delay after "OK" or "ERROR" response, refer to the following command specifications for details. The TE shall communicate with the TC35i using activated echo (ATE1), i.e. the TC35i echoes characters received from the TE. Hence, when the TE receives the echo of the first character "A" of the AT command just sent by itself it has control over both the receive and the transmit paths. This way no URC can be issued by the TC35i in between. * TC35i_ATC_V02.07 Confidential / Released Page 26 of 439 1/30/04 TC35i AT Command Set 1.8 Errors and Messages s mobile 1.8 Errors and Messages The final result codes "+CME ERROR: AT+CEER TC35i_ATC_V02.07 Confidential / Released Page 27 of 439 1/30/04 TC35i AT Command Set 2.

After this, you may want to verify the operating status: AT+CFUN? +CFUN: 1 EXAMPLE 3 Indicates that ME has entered full functionality mode. To stop CYCLIC SLEEP mode and return to full functionality: AT+CFUN? +CFUN: 5 OK AT+CFUN=1 OK Remember that this approach is not applicable to the NON-CYCLIC SLEEP mode (since the serial interface is disabled). The NON-CYCLIC SLEEP mode ends with the first wake-up event. EXAMPLE 4 To reset and restart the ME: AT+CFUN=1,1 OK ^SYSSTART or alternatively, AT+CFUN=0,1 or 5,1 or 6,1 or 7,1 or 8,1 The ^SYSSTART URC confirms that the ME has been rebooted.

Low level of the module's VDD pin and display of URC "^SHUTDOWN" verifies that the procedure has completed and the module has entered the POWER DOWN mode. Therefore, be sure not to disconnect the operating voltage until VDD is low or until URC "^SHUTDOWN" is displayed . Otherwise, you run the risk of losing data. For further details on how to turn off the module see the [2]. Notes * * Do not send any command after this command. If AT^SMSO is entered on one of the Multiplexer channels the ME closes the Multiplexer channels, terminates the Multiplexer and deactivates all other functions.

Forward "+CIEV" URCs directly to the TE. If TC35i is in online data mode, URCs are signaled via sending BREAK (100ms) and stored in a buffer. Once it is back in command mode e.g. after +++ was entered, all URCs stored in the buffer will be output. 3 0(&F) Keypad event reporting is not supported by TC35i. 0(&F) Display event reporting is not supported by TC35i. 0(&F) 2 Disable indicator event reporting.

For example, if messages shall be routed directly to one instance of the TE (set with AT+CNMI, AT^SSDA), it is not possible to activate the presentation of URCs with AT+CMER or AT+CNMI on another instance. Any attempt to activate settings that conflict with existing settings on another interface, will result in CME ERROR, or accordingly CMS ERROR.

Use of this command is outdated since additional indications and functionality are available with AT^SIND. AT+CIND supports two ways to get the values related to indicators: * Query the current status of each indicator by using the read command AT+CIND?. It returns the status no matter whether the indicator has been registered with the write command AT+CIND=[ * - Syntax Test Command AT+CIND=? Response(s) +CIND: ( Read Command AT+CIND?

Indicator is registered, indicator event report allowed. Notes * Due to its restrictive range of values, there are events when it is not entirely clear from the context, which event has led to the output of indicator "call". Rather than as an information in itself, indicator "call" should therefore be used as a trigger to look up the new call status in the list of current calls with AT commands AT+CLCC or AT^SCNI. The indicator "sounder" signals every event a tone is generated in the ME. For instance, if a waiting call produces a tone, this will be indicated. If the ME is switched on all indicators are in registered state. Use AT+CMER command to allow Indicator Event Report of all registered indicators. * * * Example ^SYSSTART AT+CPIN=9999 OK AT+CIND? +CIND: 5,99,1,0,0,0,0,0,5 The battery is either full or no battery is connected to the ME.
