About This Guide Document Structure Following this introduction is a section on basic elements important to understanding and communicating with the MP 700 Series GPS. This includes notes on the connection between the host computer and the modem. The document then presents the commands, registers, result codes, and defaults provided in the command state of the modem. Commands are often termed AT commands.
MP 700 Series GPS AT Command Reference • Characters that are required are shown in uppercase; parameters are noted in lowercase. Parameters are enclosed in angle brackets () to indicate that they should be replaced with a value. Optional parameters are described in the text, and may also be enclosed in square brackets ([]) for clarity. • Supported parameter values (either set or returned) are described in the text.
2: Modem Basics • GSM, GPRS, and EDGE • Modem modes, states, and conditions • State Transitions • Modem Buffers • Command Handling • Responses and Result Codes • Response and Result Framing • GPS data format 2 This section provides the information required to: • Establish a communications session with the modem that will allow you to enter AT commands • Understand the operating modes and states of the modem and what causes the modem to transition between them • Understand which commands are available
MP 700 Series GPS AT Command Reference establish CSD (Circuit-Switched Data) connections in areas that have GSM but no GPRS/EDGE service (assuming CSD is supported by your service provider). Establishing a communication session Any terminal emulation program can be used to create a communications session that will allow you to issue AT commands to the modem. This section describes how to use HyperTerminal, a program typically installed with Windows, to establish a session with the modem.
Modem Basics Host connection basics Hardware structure The MP 700 Series GPS has two main components: the AirCard® wireless network card and the controller board. Each of these components has its own firmware (resident software). There is a serial link between the AirCard and the controller board. All AT commands that begin with AT!MP are handled by the controller board and all others are handled by the AirCard.
MP 700 Series GPS AT Command Reference Modem-to-network connection Note: If you are developing a network application to control or monitor MP 700 Series GPS modems installed in a fleet of vehicles, it is usually best to use Always On mode. (With On Demand mode, it can be difficult to track the modems’ IP addresses.) The operating mode determines how the modem-to-network connection is established.
Modem Basics Connection Modes The MP 700 Series GPS operates in three modes: Circuit-switched data (CSD) In Circuit Switched Data (CSD) mode, the modem operates much like a landline modem. The Fallback feature must be configured to allow for this type of connection. (See !MPFBSETUP on page 41.) Packet-switched data In this mode the modem establishes a high-speed packet data connection using GPRS or EDGE service.
MP 700 Series GPS AT Command Reference Offline Disconnected from any remote terminal or network (on-hook). While in offline condition, the modem can only be in command state (without an airlink).
Modem Basics • If there is an active PAD (Packet Assembler/Disassembler) session and the PAD is configured to use TIES (Time Independent Escape Sequence), the modem switches to command state on receipt of “AT+++”. (The “AT” must be in upper case.) The command !MPPADCONF (described on page 52) is used to enable and disable TIES. When the modem changes to command state, it will issue an OK result.
MP 700 Series GPS AT Command Reference Specific settings for buffer controls are described in the relevant commands and registers. Normal configuration of the modem will not require you to adjust these settings. Data flow control The modem’s CTS and RTS lines control data flow. Where large amounts of data are being exchanged, local hardware flow control must be used to prevent buffer overflows; it is required for PPP connections. Hardware flow control is enabled by default.
Modem Basics Note: Entering incorrect syntax or a parameter outside of the specified range may have unexpected results. Defaults shown in the command tables are those for the factory settings of the modem. They are not the defaults assumed for a command issued without parameters, which are noted in the text. Registers Some registers are read only. Attempting to write to them yields an ERROR result code. Some registers store the setting of commands.
MP 700 Series GPS AT Command Reference • Quiet off (Q0) enables the modem to issue result codes following commands. Quiet on (Q1) suppresses result codes entirely; responses remain unaffected. • Verbose result codes enabled (V1) provides results in English text appended with . Verbose off (V0) returns the results as ASCII numeral codes. Numeric codes are much easier to process using software.
Modem Basics Result code framing Every command will return a result code unless the Quiet command is enabled. If Quiet is on (ATQ1, see page 102) then neither framing characters nor result code is returned. A leading is inserted ahead of the result code if Verbose is on (ATV1, see page 102). Otherwise there are no leading characters prior to the ASCII numeral result. The result code is always followed by a . There is a trailing only if Verbose is on.

3: Command Reference • Introduction • Command Types • Command Reference Table • Result Codes • Factory Default Settings 3 Introduction As described in the previous section, AT commands are available with Sierra Wireless GSM products for users of the COM serial interface. The commands allow control of Circuit Switched Data (CSD) calls and data exchange, similar to dial up modems, but without wires, and with additional commands available specific to GSM, GPRS, and EDGE.
MP 700 Series GPS AT Command Reference Command Types Note: The AT prefix does not appear in the reference tables. It is, however, required and assumed for all commands unless specifically noted otherwise. The command reference table (beginning on page 31) details the available AT commands in strict ASCII alphabetic order (including character prefixes such as !, & and +, which in ASCII fall before the letters of the alphabet).
