Preface
Because of the nature of wireless communications, trans-
mission and reception of data can never be guaranteed. Data
may be delayed, corrupted (i.e., have errors) or be totally lost.
Although significant delays or losses of data are rare when
wireless devices such as the Sierra Wireless modem are used in
a normal manner with a well-constructed network, the Sierra
Wireless modem should not be used in situations where
failure to transmit or receive data could result in damage of
any kind to the user or any other party, including but not
limited to personal injury, death, or loss of property. Sierra
Wireless, accepts no responsibility for damages of any kind
resulting from delays or errors in data transmitted or received
using the Sierra Wireless modem, or for failure of the Sierra
Wireless modem to transmit or receive such data.
Do not operate the Sierra Wireless modem in areas where
blasting is in progress, where explosive atmospheres may be
present, near medical equipment, near life support equipment,
or any equipment which may be susceptible to any form of
radio interference. In such areas, the Sierra Wireless modem
MUST BE POWERED OFF. The Sierra Wireless modem can
transmit signals that could interfere with this equipment.
Do not operate the Sierra Wireless modem in any aircraft,
whether the aircraft is on the ground or in flight. In aircraft, the
Sierra Wireless modem MUST BE POWERED OFF. When
operating, the Sierra Wireless modem can transmit signals that
could interfere with various onboard systems.
Note: Some airlines may permit the use of cellular phones while the
aircraft is on the ground and the door is open. Sierra Wireless
modems may be used at this time.
The driver or operator of any vehicle should not operate a
computer or any other device connected to the Sierra Wireless
modem while in control of a vehicle. Doing so will detract
from the driver or operator's control and operation of that
vehicle. In some states and provinces, operating such commu-
nications devices while in control of a vehicle is an offence.
The information in this manual is subject to change without
notice and does not represent a commitment on the part of
Sierra Wireless. SIERRA WIRELESS AND ITS AFFILIATES
SPECIFICALLY DISCLAIM LIABILITY FOR ANY AND ALL
DIRECT, INDIRECT, SPECIAL, GENERAL, INCIDENTAL,
CONSEQUENTIAL, PUNITIVE OR EXEMPLARY DAMAGES

Introduction
This reference details the Attention (AT) command set
supported by the MP 700 Series GPS rugged wireless modem.
You should be familiar with the use of AT commands with
standard wireline modems to use this document.
The Sierra Wireless GSM products present two methods of
controlling the modem: AT commands and CnS (Control and
Status) language. Some features or capabilities of the modem
require the use of CnS. This document presumes that the AT
interface is the only interface available to you; features
requiring CnS are not discussed.
References
This guide covers only the command set used by the
MP 700 Series GPS and does not deal with operational use.
Refer to the product documentation for instructions on using
your modem.
Not all commands include detailed descriptions. Commands
are implemented to be compliant with industry standards and
reference is often made to the following standards:
• IS-131 (Data Transmission Systems and Equipment -
Extensions to Serial Asynchronous dialing and Control)
• EIA/TIA-592 (Asynchronous Facsimile DCE Control
Standard, Service Class 2)
• EIA/TIA/IS-134 (Amendments to TIA-592 to Support T.30-
1993 (Facsimile protocol standard))
Electronic copies of these standards can be purchased at the
ANSI Electronic Standards Store at: webstore.ansi.org. ANSI
Customer Service will respond to inquiries about standards
