11 11: 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, www.itu.int ).
See Table 11-1 below.
• Control SMS functions for devices on GSM/WCDMA networks
(
3GPP TS 27.005 , available on the 3GPP web site,
www.3gpp.org )
See Table 11-2 on page 133.
• Control devices operating on GSM/WCDMA networks ( 3GPP TS
27.007, available on the 3GPP web site, www.3gpp.org )
See Table 11-3 on page 134.
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 later chapters—the
descriptions for these commands link to those detailed entries (for
example,
&V
in Table 11-1 on page 131).
