1. INTRODUCTION

Scope

This document covers the more significant standard and proprietary AT commands provided by Telit's modules. Several module features are described and for each one of them the related AT commands are explained through examples. This document is not an exhaustive description of the AT commands implemented on the Telit's modules series, its target is only to give you an entry point to the AT commands world.

Audience

The present User Guide is addressed to users that need to learn and use quickly standard and proprietary AT commands. The reader can learn the use of the AT commands through simple examples shown in the document, and then deepen the interested AT commands reading the documents [1]/[17] in accordance with the used module.

Parameter Description
<n> 0~127 Default value is 13 (Corresponding ASCII character CR
carriage return )
Notice: if change this value, it possible to affect the
execution of the AT command.
Example
ATS3=32
OK
ATS32?
32
OK
In this point, the AT command line terminator has become a
