These commands refer to ETSI GSM Standard 07.07 1.7 and GSM Standard 07.05 1.7; nevertheless, some of the commands implemented in the SAGEM GSMR mobile phones may not be fully compatible with the ETSI recommendations. 1.2 handling of commands Following rules are applied when handling a command line (according to the V.25 ter Recommendation 1.7): A command line is detected if it is started with the prefix “AT”. The command line is interpreted when the carriage return character (0x0D) is encountered. A new command line is correctly handled if it is issued after reception of the entire result code in response to the preceding command line. The commands in the command line are proceeded one after the other. The process stops at the first wrong command. When an incorrect or undefined command is detected, an ERROR or +CME ERROR result code is sent back. This rule does not apply for the following commands in order to be compatible with most commercial softwares: C, DL, DS, F, L, M, N, P, T, X, Y, &A, &G, &J, &M, &N, &P, &Q, &R, &S, &U. When the PIN is not ready, a restricted set of AT commands are available. These commands are: B, D112, E, I, Q, S0, S2, S7, V, Z, \N0, \N4, \V, +CGMI, +CGMM, +CGMR, +CGSN, +CIND, +CPAS, +CPIN, +GMI, +GMM, +GMR, +IPR, &C, &D, &F, &K, &V, &W When optional parameters are omitted, the assumed value is zero for simple commands and the previous value for extended commands (AT+…). Some commands that require time to execute may be aborted while in progress. These commands are aborted by transmitting any character. Commands that may be aborted are: A, D, +CAJOIN, +COPS 1.3 Result codes There are three types of result codes that may be issued by the ME: final, intermediate and unsolicited. A final result code indicates the completion of a full command line. When a final result code is issued, the ME is able to handle a new command line. An intermediate result code is a report of the progress of a command. An unsolicited result code indicate the occurrence of an event not directly associated with the issuance of a command from the DTE. The following table illustrates all unsolicited result codes sent from the mobile to the application. Verbose详述 result code Description Type +CCCM: Current Call Meter value Refer subclause 4.14 Unsolicited任意型的 +CCWA: ,,[,] Call Waiting Refer subclause 4.10 Unsolicited +CIEV: , Indicator Event Refer subclause 5.7 Unsolicited +CKEV: , Keypad Event Refer subclause 5.7 Unsolicited +CLIP: ,[,,[,]] Calling Line Identity身份 Refer subclause 4.6 Unsolicited任意型的 +CME ERROR: Mobile Equipment Error Refer subclause 7.2 Final +COLP: ,[, ,[,]] Connected Line Identity Refer subclause 4.8 Intermediate中级的 +CR: Service Report Refer subclause 3.4 Intermediate +CREG: [,,] Network Registration Refer subclause 4.2 Unsolicited +CRING: Incoming Call Notification通知 Refer subclause 3.6 Unsolicited +CSSI: [,] Supplementary追加的 Service Notification Refer subclause 4.15 Intermediate +CSSU: [,[,,[,,]]] Supplementary Service Notification Refer subclause 4.15 Unsolicited +CUUS1I: User-to-User Refer subclause 4.13 Intermediate +CUUS1U: User-to-User Refer subclause 4.13 Unsolicited +CUSD: [,,] Unstructured Supplementary Service Data Refer subclause 4.12 Unsolicited BUSY Busy signal detected Refer subclause 2.7 Final CONNECT Connection has been established Refer subclause 3.1 Intermediate CONNECT 2400 Connection 2400 bps Refer subclause 3.1 Intermediate CONNECT 4800 Connection 4800 bps Refer subclause 3.1 Intermediate CONNECT 9600 Connection 9600 bps Refer subclause 3.1 Intermediate ERROR command not accepted Final NO CARRIER connection terminated Final OK Acknowledges承认 execution of a command line Final RING incoming call signal from network Unsolicited +CAULEV: Uplink Status Refer subclause 6.1.8 Unsolicited +CACSP: ,,, Call State Attribute属性 Refer subclause 6.1.10 Unsolicited +CANCHEV: NCH Support Refer subclause 6.1.11 Unsolicited Note: For mobile originated voice calls, activating the COLP result code enables the presentation of the intermediate result codes reporting the progress of the call establishment. The OK final result code is issued at the connection. When the COLP presentation is disabled, the final result code OK is sent back if the setup is successful and no intermediate result code will be issued. 1.4 Default serial link speed The default serial link speed is 4800 bps. The serial link is set to the default speed: when the ME is powered ON, at a OFF-to-ON transition of the DTR if &D2/&D3 is selected, after a transparent data call closing. (after NO CARRIER or OK final result codes). 1.5 Implementation of indexes SMS and phonebook entries登录 can be stored in either SIM card memories or mobile phone memory. For each type of memory, a valid range of indexes are defined. These ranges may vary according to SIM / mobile phone type. For instance, + for SMS: When the preferred首选的 memory storage is set to SM, the indexes begin from 1 to 10 (if the SIM card supports up to 10 SMS). When the preferred memory storage is set to ME, the indexes begin from 900 to 909 (if the Mobile equipment supports up to 10 SMS). When the preferred memory storage is set to MT, the indexes begin from 1 to 10 (if the SIM card supports up to 10 SMS) and jump to 900 to 909 (if the Mobile equipment supports up to 10 SMS). The reason of this implementation is to have the same numbering from a mobile point of view and a TE point of view for the user. + for phonebook management: When the preferred memory storage is set to SM, the indexes begin from 1 to 100 (if the SIM card supports up to 100 phonebook entries). When the preferred memory storage is set to ME, the indexes begin from 900 to 999 (if the Mobile equipment supports up to 100 phonebook entries). When the preferred memory storage is set to MT, the indexes begin from 1 to 100 (if the SIM card supports up to 100 phonebook entries) and jump to 900 to 999 (if the Mobile equipment supports up to 100 phonebook entries). The reason of this implementation is to have the same numbering from a mobile point of view and a TE point of view for the user. 1.6 Abbreviations缩写 For the purposes of the present document, the following abbreviations apply: AT ATtention;

Changing the parameter takes effect immediately in both the command and online command states. AT&C0 : DCD Line always ON AT&C1 : DCD Line follows the carrier (DCD ON during online mode). 2.7.13 Circuit 108 (Data Terminal Ready) behaviour AT&D This parameter determines how the DCE responds when circuit 108/2 state changes. AT&D0: Ignore DTR AT&D2: upon an ON-to-OFF transition of circuit 108/2, the mobile clears the ongoing call. Automatic answering is disabled while circuit 108/2 remains OFF. MRM specificity: upon an OFF-to-ON transition of circuit 108/2, the speed of the serial link is reset to the default speed (4800 bps). AT&D3: upon an ON-to-OFF transition of circuit 108/2, the mobile clears the ongoing call. Automatic answering is disabled while circuit 108/2 remains OFF. MRM specificity: upon an OFF-to-ON transition of circuit 108/2, the speed of the serial link is reset to the default speed (4800 bps) and the active profile is reset to the user configuration (implicit ATZ). 2.7.14 Fixed DTE rate AT+IPR Command Possible response(s) +IPR= +IPR? +IPR: +IPR=? +IPR: (list of supported s) This command specifies the data rate at which the DCE will accept command. Defined values : 2400, 4800, 9600, 19200 bps Note: This command modifies the current serial link speed but not the default serial link speed. 2.7.15 Repetition of the previous command A/ A/ : repetition of the previous command 3 Call control commands 3.1 Simple call control commands 3.1.1 Dial ATD[ATDP][ATDT][;] This command instructs the mobile to originate a call. Result codes: CONNECT 2400 CONNECT 4800 CONNECT 9600 Connection has been successfully established. This result code is transmitted immediately after circuit 109 is turned on. NO CARRIER Connection cannot be established, or was aborted by reception of an additional character from the DTE. See +CEER for error report. ERROR Call cannot be originated. BUSY Called party is busy. OK Dial command is aborted by reception of an additional character from the DTE. Or Dial command is aborted by the DTE turning off circuit 108/2 and &D2 or &D3 is selected. Or the dial string is terminated by a semicolon character (voice call) 3.1.2 Answer ATA This command instructs the mobile to answer a call. This command may be aborted by additional characters from the DTE. 3.1.3 Hook Control ATH This command releases the subscriber from all calls (except a possible waiting call). If a call is in progress and not established (incoming or outgoing call), the ATH command releases only this call. 3.1.4 Return to online data state ATO This command causes the mobile to return to online data state and issue a CONNECT [] result code. 3.1.5 Automatic answer ATS0 ATS0=n : Answer a Data / Fax call after n rings. If n=0, automatic answer is disabled 3.1.6 Online mode control ATS2 ATS2=n : control the possibility to go to online command mode. Defined Values 0 <= n < 128 : Detection of the escape sequence +++ leads to a transition from online data mode to online command mode. 128 <= n < 255 : Escape Sequence +++ ignored. 3.1.7 Data mode selection AT\N[0|4] AT\N4 or AT\N6 : Secured mode (RLP) AT\N0 : Transparent mode 3.1.8 Bearer capability ATBi ATBi : Bearer Capability (data rate and type on GSM interface) selection : ATB7 ATB11 ATB13 ATB25 ATB27 ATB29 Analogic modem 2400 (V22BIS) Analogic modem 4800 (V32) Analogic modem 9600 (V32) UDI 2400 (ISDN call) UDI 4800 (ISDN call) UDI 9600 (ISDN call) 3.1.9 Data flow control AT&Ki AT&K0 : no flow control AT&K3 : hardware flow control 3.1.10 Connect format AT\Vi AT\V[0|1] : 0 = CONNECT message only, 1 = /RLP after CONNECT message 3.2 Select bearer service type +CBST Command Possible response(s) +CBST=,, +CBST? +CBST: ,, +CBST=? +CBST: (list of supported s),(list of supported s),(list of supported s) Description Set command selects the bearer service with data rate , and the connection element to be used when data calls are originated (refer GSM 02.02 1.7). Test command returns values supported by the TA as compound values. Defined values : 0 autobauding (automatic selection of the speed; this setting is possible in case of 3.1 kHz modem and non-transparent service) 4 2400 bps (V.22bis) 6 4800 bps (V.32) 7 9600 bps (V.32) 68 2400 bps (V.110) 70 4800 bps (V.110) 71 9600 bps (V.110) All other values will return ERROR : 0 asynchronous modem (all other values will return ERROR) : 0 transparent mode 1 secured mode (RLP) Note: The parameter sets the mode for both incoming and outgoing data calls. The parameter sets the radio user rate for outgoing calls and for incoming secured calls. For incoming transparent calls, the ME adapts to the user rate presented by the network. If the connection is successful, the speed of the serial link is set to the user rate just after the CONNECT message. At the end of the call, the serial link is set to the default speed. 3.3 Radio link protocol +CRLP Command Possible response(s) +CRLP=[[,[,[,[,[,]]]]]] +CRLP? +CRLP: ,,,[,[,]] +CRLP=? +CRLP: (list of supported s),(list of supported s), (list of supported s),(list of supported s)[, [,(list of supported s)]] Description Radio link protocol (RLP) parameters used when non-transparent data calls are originated may be altered with set command.
