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.
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.
These AT Commands are related to ITU-T (International Telecommunication Union, Telecommunica- tion sector) V.25ter document. MC35 supports 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! 2.1 A/ Repeat previous command line...

AT Command Set Full functionality. If the ME is in one of the two CYCLIC SLEEP modes you can issue AT+CFUN=1 to stop power saving and return to full functionality. Keep in mind that, unlike the reset command described below, this action does not restart the ME but only changes the level of functionality.
Page 80
AT Command Set Example 2 To set the ME to NON-CYCLIC SLEEP mode enter AT+CFUN=0 When, for example, an SMS is being received and indicated by an unsolicited result code (URC), the ME wakes up to full operation. Note that the URC used in this example will appear +CMTI: "SM",5 only if CMTI=1,1 was configured before.
AT Command Set 4.11.1 Wake up the ME from SLEEP mode A wake-up event is any event that switches off the SLEEP mode and causes the ME to return to full functionality. In short, it takes the ME back to AT+CFUN=1. Definitions of the state transitions described in Table 7: Yes = ME exits SLEEP mode.

AT Command Set turns to the AT command mode. 3. There are various options to switch from data mode to command mode: a) Escape sequence +++ b) Circuit 108/2 (DTR) changes from ON to OFF, reaction depends on command at&d (caution if AT&D0: TA ignores status on DTR). c) The message Modem Status Command (MSC) for control channel is defined by the multiplexer protocol GSM07.10.
Siemens GSM engines support the registers S0 - S29. You can change S0, S3, S4, S5, S6, S7,S8, S10 and S18 using the related ATSn commands (see starting from pg. 32). MC35 allows to use the GPRS commands on all logical channels, but to remain compatible to fu- ture releases it is recommended to use them on channel 1 only.
AT Command Set 4.29 AT+COPN Read operator names Test command Response AT+COPN=? Execute command TA returns the list of operator names from the ME. Each operator code <nu- mericn> that has an alphanumeric equivalent <alphan> in the ME memory is AT+COPN returned.
AT Command Set 4.30 AT+COPS Operator selection This command can be used to query the present status of the ME's network registration and to de- termine whether automatic or manual network selection shall be used. Automatic mode: Lets the ME automatically search for the home operator. If successful the ME registers to the home network and enters the IDLE mode.

AT Command Set MC35 offers various options to verify the present status of network registra- tion: For example, the AT+COPS? (Chapter 4.30) command indicates the currently used network. With AT+CREG (Chapter 4.41) you can also check the current status and activate an unsolicited result code which appears whenever the status of the network registration changes (e.g.
AT+CPIN?), i.e. it is now waiting for the Master Phone Code. This is an 8-digit device code associated to the IMEI number of the mobile which can only by obtained from the manufacturer or provider. When needed, contact Siemens AG and request the Master Phone Code of the specific module.
Page 115
AT Command Set SIM locks: These are factory set locks, such as "PF", "PN", "PU", "PP", "PC". An 8-digit unlocking code is required to operate the mobile with a different SIM card, or to lift the lock. The code can only be obtained from the provider. Failure to enter the password is subject to the same timing algorithm as the Master Phone Code (see Table 10).

AT Command Set 8 Siemens defined AT commands for enhanced functions Self-defined commands do not have to be implemented in accordance with the official syntax. The “+C” string can therefore be replaced by “^S” (“^” = 0x5E). If a self-defined command with the same syntax will be included in future in the GSM recommendations, the command can be addressed with both strings.
AT Command Set 8.2 AT^MONI Monitor idle mode and dedicated mode Test command Response AT^MONI=? ^MONI: (list of supported < period > s) OK Write command This command can be used to retrieve information of the serving/dedicated cell automatically every n seconds. It is cancelled by any character sent to serial port AT^MONI[=<pe except if autobauding is enabled (+IPR=0).

Reference Note · The parameters LAC and cell are presented as hexadecimal digits, the remain- Siemens ing parameters are composed of decimal digits. · If the radio cell changes during a connection, the parameters PWR and RXLev of the ‘Serving Cell’ part cannot be updated under certain conditions and, there- fore, are left blank (see also +CREG, pg 123).
Reference Note · Cell information can be issued in the form of unsolicited result codes Siemens (related to <period>), or it can be queried directly using the Execute command AT^MONI. In the first case, the ME activates its RING line (Logic “1”) for one second to send the URC to the connected applica-...
