1 1: About this Guide • Introduction • Result codes • Terminology and acronyms • Current firmware versions • Document structure • Conventions Introduction This document describes standard and proprietary AT commands that are available for users of UMTS AirCard modems, Compass modems, and Mini Card embedded modules. The standard 3GPP AT commands for UMTS devices are described in two standards documents available from the 3GPP (3rd Generation Partnership Project) web site, www.3gpp.org: • TS 27.
Supported AT Command Reference Result codes Result codes are not shown in the command tables unless special conditions apply. Generally the result code OK is returned when the command has been executed. ERROR may be returned if parameters are out of range, and will be returned if the command is not recognized or is not permitted in the current state or condition of the modem.
About this Guide Upgrading If your modem firmware is an earlier version, you can acquire updated firmware by contacting your account manager. Document structure This document assumes you have the 3GPP TS 27.007 AT command documentation (see page 9). This reference includes a chapter covering Supported 27.007 AT commands, as well as the proprietary commands listed in the tables below. Each table corresponds to one chapter in this guide.
