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.

are implemented to be compliant with industry standards and
reference is often made to the following standards:
