7: Supported GSM/WCDMA AT Commands

This chapter identifies standard AT commands that are supported by

most NETGEAR AirCard devices. These commands:

• Control serial communications over an asynchronous interface

(ITU-T Serial Asynchronous Dialling and Control (Recommen-

dation V.250), available on the International Telecommunication

Union web site, www.itu.int).

See Ta bl e 7 -1 below.

• Control SMS functions for devices on GSM/WCDMA networks

(3GPP TS 27.005, available on the 3GPP web site,

www.3gpp.org)

See Ta bl e 7 -2 on page 39.

• Control devices operating on GSM/WCDMA networks (3GPP TS

27.007, available on the 3GPP web site, www.3gpp.org)

See Ta bl e 7 -3 on page 40.

The tables below identify whether each command is supported on

NETGEAR UMTS devices. An “N/A” in the Supported column of the

table indicates that the command is related to a feature (such as

voice) that is not available on the modems.

Commands that are partially supported include descriptions

identifying any limitations on command usage. Also, some

commands are described in more detail in later chapters—the

descriptions for these commands link to those detailed entries (for

example,

&V in Tabl e 7- 1 on page 37).
