Chapter 1 – Introduction 1.5 Communication between Customer Application and the MTSMC-E and E1 Leaving hardware flow control unconsidered the Customer Application (TE) is coupled with the MC75i (ME) via a receive and a transmit line. Since both lines are driven by independent devices collisions may (and will) happen. For example, if the TE issues an AT command the MC75i starts sending a URC. This will probably cause the TE to misinterpret the URC being part of the AT command's response.
Chapter 1 – Introduction Several problems resulting from the use of GSM alphabet with ASCII terminal equipment: • “@” character with GSM alphabet value 0 is not printable by an ASCII terminal program (e.g., Microsoft© HyperTerminal®). • “@” character with GSM alphabet value 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()”.
Chapter 1 – Introduction 1.6.1 GSM Alphabet Tables and UCS2 Character Values This section provides tables for the GSM 03.38 alphabet supported by the ME. Below any GSM character find the corresponding two byte character value of the UCS2 alphabet. Figure 1.1: Main character table of GSM 03.38 alphabet 1. 2. This code is an escape to the following extension of the 7 bit default alphabet table. This code is not a printable character and therefore not defined for the UCS2 alphabet.
Chapter 1 – Introduction Figure 1.2: Extension character table of GSM 03.38 alphabet 1. This code value is reserved for the extension to another extension table. 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.
Chapter 1 – Introduction 1.6.2 UCS2 and GSM Data Coding and Conversion for SMS Text Mode This section provides basic information on how to handle input and output character conversion for SMS text mode and Remote-SAT if the internal (TA) and external (TE) character representation differ; e.g., if the Data Coding Scheme and the TE character use different coding. 1.6.2.
Chapter 1 – Introduction 1.6.2.2 Implementing Input of Terminal Data to SIM (Direction TE to TA) Used Character DCS = 7 bit DCS = 8 bit DCS = 16 bit Set GSM Data UCS2 GSM UCS2 Case 1 GSM (1:1) Case 4 GSM to IRA (1:4) Case 2 IRA to 8 bit (2:1) Case 5 8 bit to IRA (1:4) Case 3 IRA to 16 bit (4:2) Case 6 UCS2 to IRA (2:4) Note: The ratio between the number of input characters and bytes stored on the SIM is given in parentheses.
Chapter 1 – Introduction 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; e.g., 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”), waiting calls, received short messages, changes in temperature, network registration etc.
Chapter 1 – Introduction 1.9 Serial Interface Flow Control Flow control is essential to prevent loss of data or avoid errors when, in a data 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 until it catches up. There are basically two approaches to regulate data flow: Software flow control and hardware flow control.
Chapter 1 – Introduction Also, please consider that RTS/CTS flow control cannot stop the data stream coming from the network, e.g.,in a GPRS or fax connection. So the lack of appropriate hardware flow control increases the risk of losing data packets if, like in the case of UDP, the connection protocol has no or only minimum error handling functions. Other network protocols are using high level flow control mechanisms. For example, to prevent loss of data the TCP protocol uses retransmission algorithms. 1.
Chapter 2 – Configuration Commands Chapter 2 – Configuration Commands The AT commands described in this chapter allow the external application to determine the modem’s behavior under various conditions. 2.1 AT&F Set All Current Parameters to Manufacturer Defaults Description: Syntax: Parameter: AT&F sets all current parameters to the manufacturer defined profile.
Chapter 2 – Configuration Commands 2.2.1 AT&V Responses The following table shows different kinds of responses depending on whether or not the PIN is entered.
Chapter 2 – Configuration Commands 2.4 ATQ Set Result Code Presentation Mode Description: Syntax: Parameters: Notes: • • • • This command determines whether or not the TA (terminal adapter) transmits any result code to the TE (terminal equipment). Other Information text transmitted in response is not affected. Exec Command: ATQ[] Response: If = 0: OK If = 1: (none) 0 DCE (Data Communication Equipment) transmits result code. Factory default; it can be restored to 0 with AT&F.
Chapter 2 – Configuration Commands 2.6 ATX Set CONNECT Result Code Format and Call Monitoring Description: Syntax: Parameter: Notes: • • • • ATX determines whether or not the TA (terminal adapter) detects the presence of dial tone and busy signal and whether or not the TA transmits particular result codes. Exec Command: ATX[] Response: OK ERROR 0 CONNECT result code only returned, dial tone and busy detection are both disabled.
Chapter 2 – Configuration Commands 2.8 ATZ Set all Current Parameters to User Defined Profile Description: Syntax: Parameter: ATZ sets all current parameters to the user profile stored with AT&W. If a connection is in progress, it will be terminated. All defined GPRS contexts which are not activated or not online will be undefined if the nonvolatile storage of the CGDCONT settings is not activated by the AT^SCFG parameter "GPRS/Persistent Contexts" (see AT+CGDCONT).
Chapter 2 – Configuration Commands 2.9 AT+CFUN Set Phone Functionality Description: This command serves to control the functionality level of the mobile equipment (ME). It can be used to reset the ME, to choose one of the SLEEP modes, or to return to full functionality. Intended for power saving, SLEEP mode reduces the functionality of the ME to a minimum and thus minimizes the current consumption.
Chapter 2 – Configuration Commands 7 CYCLIC SLEEP mode: In this mode, the serial interface is shortly enabled during paging. If characters are recognized on the serial interface, the ME stays active for 2 seconds after the last character was sent or received. ME exits SLEEP mode only, if AT+CFUN=1 is entered. 9 CYCLIC SLEEP mode: In this mode, the serial interface is shortly enabled while CTS is active.

Chapter 2 – Configuration Commands Power Saving Mode 9 Timeout This parameter can be used to query or configure the wake up time for power saving mode 9 (see AT+CFUN with parameter =9). The granularity of the timeout value is 100ms (i.e. a value of 10 equal 1 second). The minimum timeout value that can be applied is 5, but accuracy is only guaranteed for timeout values greater than 20. Parameter is global for the ME, volatile, and will not be reset by AT&F. 5.....
Chapter 2 – Configuration Commands Preferred Radio Band(s) The write command will trigger the band selection, starting with the user preference specified by . This means bands contained in will be searched first, regardless of the standard band combination of the current country. The final result of the band selection can be read from .
Chapter 2 – Configuration Commands Continuous Network Search Mode This parameter can be used to influence the time the ME takes to register to the network. The parameter is global for the ME, volatile, and will not be reset by AT&F. 0 Normal. Default (This is powerup default value which is not stored at power down). When trying to register to a network the ME sleeps longer than in "Fast mode" before restarting a network scan.
Chapter 2 – Configuration Commands Initial Retransmission Timeout (IRT) 1....60 This parameter determines the time (in seconds) the TCP/IP stack will wait before starting the first retransmission of packets during the initial connection establishment phase. Default = 3 (This is the factory default value and will be restored to 5200 with AT&F. It is also a powerup default value which is not stored at power down).
Chapter 2 – Configuration Commands Transaction/TCP (T/TCP) This parameter concerns T/TCP, an extension of TCP to provide a transactionoriented service. T/TCP is described in RFC 1644. The value set with enables or disables T/TCP. The parameter is global for the ME. Use of the power up value is recommended. 0 Disable T/TCP extension. Default (This is a powerup default which is not stored at power down). 1 Enable T/TCP extension.
Chapter 2 – Configuration Commands URC RING Line This parameter can be used to control the behavior of the RING line to indicate URCs (both for idle interfaces and, if configured by the parameter “URC/Datamode/Ringline”, if link is reserved) and, if configured, the indicator for incoming IP packets (see parameter “GPRS/RingOnIncomingData” (). Parameter is local for the interface, volatile and will not be reset by AT&F. off URC is not indicated by RING.
Chapter 2 – Configuration Commands Examples: Example 1 – Use of AutoExec: Enable sending of a short message (SMS) on next DTR activation (OFF-ON transition). Sent SMS is assumed to be stored at first location of storage selected with AT+CPMS and AT^SSMSS, i.e. SMS may be sent either from SIM or ME storage. Also refer to AT+CMSS and AT+CMGW. Since SMS transmission and ongoing calls are possible at the same time there is no need to wait until all calls have ended (=0).

Chapter 4 – Serial Interface Control Commands 4.6 AT+IFC Flow Control Description: This command controls the flow control mode separately for each data direction (send and receive). In contrast to this, flow control settings made with AT\Q are identical for both directions. AT+IFC and the AT\Q are designed to configure only the TA. The TE must also be configured. When programming the TE, bear in mind that the flow control mode set on the TA must be compliant with the flow control method set on the TE.
Chapter 4 – Serial Interface Control Commands 4.7 AT+ICF Character Framing Description: AT+ICF controls character framing and parity format used for receiving and transmitting data via the device's asynchronous serial interface (UART).
Chapter 4 – Serial Interface Control Commands 4.8 AT+ILRR Set TE-TA Local Rate Reporting Description: AT+ILRR controls whether or not the intermediate result code “+ILRR” is transmitted from the TA to the TE while a connection is being set up. The result code indicates the local rate. It is issued before the final result code of the connection; e.g., CONNECT is transmitted to the TE.
Chapter 4 – Serial Interface Control Commands 4.9 AT+IPR Bit Rate (was called Set Fixed Local Rate) Description: The command AT+IPR can be used to set and query the bit rate of the device's asynchronous serial interface (UART). The test command returns the values of the supported automatically detectable bit rates and the values of the supported fixed bit rates. The read command returns the current bit rate of the interface. The write command specifies the bit rate to be used for the interface.
Chapter 4 – Serial Interface Control Commands 4.9.1 Autobauding To take advantage of autobaud mode specific attention must be paid to the following requirements: • Synchronization between TE and TA: Ensure that TE and TA are correctly synchronized and the bit rate used by the TE is detected by the TA. To allow the bit rate to be synchronized simply use an "AT" or "at" string. This is necessary when you start up the ME while autobauding is enabled.
Chapter 4 – Serial Interface Control Commands 4.10 AT^STPB Transmit Parity Bit (for 7E1 & 7O1 Only) Description: This command is intended for use with 7E1 and 7O1 only.

A “drop listing” consists of a single line containing the number of messages in the mail drop list followed by the total size of the mail drop list in bytes. Each drop listing will be finished by a so-called “dotline”, i.e. a new line with just a single dot. “2“ List command.
Chapter 10 – Internet Service Commands 10.4 AT^SISI Internet Service Information Description: Syntax: AT^SISI serves to monitor the status of Internet service profiles defined with AT^SISS. The AT^SISI read command requests the current status of all defined Internet service profiles. The AT^SISI write command requests the status of the specified Internet service profile. If the specified service profile is not defined yet, "+CME ERROR" is returned.
Chapter 10 – Internet Service Commands 10.5 AT^SISO Internet Service Open Description: The AT^SISO write command starts the Internet session configured by the service profile. All further steps needed to control the session depend on whether you are using URC mode or polling mode. The AT^SISO read command returns the current status of all services.
Chapter 10 – Internet Service Commands Internet service state. Please note, that the state of an Internet service may influence the state of the serial DCD line. For details see description of value 2 for parameter of command AT&C. 2 Allocated. Service profile resources are allocated; i.e., at least the service type has been set (parameter , value “srvType” of AT^SISS). The service is not opened, but ready for configuration.
Chapter 10 – Internet Service Commands • • • • 6, with an error being returned no earlier than after sending the first AT^SISR or AT^SISW command. In URC mode, an error URC, such as "Host not found" would be received in this situation, but in polling mode the only way to detect the state is using AT^SISI or, alternatively, AT^SISO.
Chapter 10 – Internet Service Commands Host 1 accepts the Socket connection request: at^siso=0 Host 1 accepts the connection request, where 0 is the ID of the dynamically assigned service profile. OK ^SISW: 0, 1 The URC indicates that data transmission to the remote client is possible. If the remote client has already sent some data the additional URC ^SISR: 0,1 is displayed. at^siso? Query the current status of services. ^SISO: 0, “Socket”,”4”,”4”,”0”,”0”,”10.10.0.187:65534”,”10.10.0.
Chapter 10 – Internet Service Commands 10.7 AT^SISR Internet Service Read Data Description: Syntax: The AT^SISR command either triggers a read operation (download) or queries the number of bytes in the internal buffer. The AT^SISR write command may return the following errors: • "+CME ERROR: operation failed" if there is a problem on application, socket, PPP or GPRS/GSM level. The AT^SISE command and the "^SIS" URC offer additional error information. • "+CME ERROR: operation temporary not allowed"; e.g.
Chapter 10 – Internet Service Commands Further write attempts with AT^SISR are denied as long as the is unequal 0 or is not omitted. In this case the service returns "+CME ERROR: operation of service temporary not allowed". 0 Indicates that all bytes of the current UDP datagram are read. 1...(max. data size)-1 Indicates that the currently read UDP datagram is not yet complete. The displayed value is the remaining number of bytes.
Chapter 10 – Internet Service Commands 10.8 AT^SISW Internet Service Write Data Description: The AT^SISW command triggers a write operation (upload) and queries the amount of data already sent, but not acknowledged at the TCP layer. The write operation may be run in binary mode, or in interactive text mode. The AT^SISW write command may return the following errors: • "+CME ERROR: operation failed" if there is a problem on application, socket, PPP or GPRS/GSM level.
Chapter 10 – Internet Service Commands • BACKSPACE ("\x08") deletes the last given character, • CTRL-Z ("\x1a") terminates the input, • ESC ("\x1b") aborts the command. An is ignored in this case. The V.25 command ATE also controls the echo mode of the interactive text mode. If echo is enabled (ATE1) all characters are echoed until is reached.
Chapter 10 – Internet Service Commands 10.9 AT^SICO Internet Connection Open Description: The AT^SICO write command opens a connection profile (also referred to as bearer). Unlike the AT^SISO command, which starts a connection profile and the service profile bound to it, AT^SICO activates only the selected connection profile. Another difference over AT^SISO is that AT^SICO disables the inactivity timeout of the selected connection profile and, therefore, sets the "inactTO" value to -1 (see also AT^SICS).
Chapter 10 – Internet Service Commands 10.10 AT^SICC Internet Connection Close Description: The AT^SICC write command releases a connection opened with AT^SICO and restores the previously set inactivity timeout "inactTO" of the selected connection profile. The command returns an error if any services are bound to this profile. Before using the AT^SICC write command be sure that all services were closed with AT^SISC.
Chapter 10 – Internet Service Commands Parameters: "Ping" “Ping“ Service type. 0...5 Internet connection profile identifier defined with parameter of AT^SICS. Target host name or IP address for pinging (i.e. 192.168.1.3). 1...30 200..10000 Number of ping requests (ICMP Echo Requests). Default = 1 (This is the default value if the parameter is omitted (1 will be assumed).
Chapter 10 – Internet Service Commands 10.12 AT^SISE Internet Service Error Report Description: Syntax: The AT^SISE write command returns the current error status of the specified Internet service profile. If the service profile is not defined or the value is invalid "+CME ERROR" response is returned. The error status is identical to the content of the "^SIS" URC last issued. If a service fails the commands AT^SISR or AT^SISW will return an error response.
Chapter 10 – Internet Service Commands 10.13 Internet Service URC "^SIS" Description: This section first describes the syntax and the parameters of the "^SIS" URC. The second part consists of tables listing the information elements delivered within the "^SIS" URC and the command response of AT^SISE. The presentation of the "^SIS" URC containing the parameter =0 can be disabled or enabled depending on whether polling mode or URC mode is preferred.
Chapter 10 – Internet Service Commands 10.13.1 Information Elements Related to the Service Application The following table lists URC information elements which may be returned by all supported services within the "^SIS" URC and the command response of AT^SISE.
