15: Supported GSM/WCDMA AT Commands
This chapter identifies standard AT commands that are supported by
most Sierra Wireless AirPrime 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,
).
See
•
Control SMS functions for devices on GSM/WCDMA networks
(
3GPP TS 27.005
, available on the 3GPP web site,
See
•
Control devices operating on GSM/WCDMA networks (
3GPP TS
27.007,
available on the 3GPP web site,
See
The tables below identify whether each command is supported on
Sierra Wireless 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 other chapters—the
descriptions for these commands link to those detailed entries (for
