MC55 AT Command Set

14.1 AT^SSTA

Command Description

s

mobile

The read command can be used to request the current operating status and the used alphabet of the Remote- SAT interface.

The write command is used to activate the AT command interface of the SIM Application Toolkit in the MC55 and needs to be issued after every power on. However, removing and inserting the SIM does not affect the activation status.

SAT commands which are not using the AT interface (non MMI related SAT commands , e.g. PROVIDE LOCAL INFORMATION) could be executed without activating Remote-SAT.

0	RESET
1	OFF
2	IDLE

4	WAIT
<Alphabet>(num)

<SatProfile>(str)

SAT profile according to GSM 11.14 [19].

The profile tells the SIM Application which features (e.g. proactive commands) are supported by the SIM Appli- cation Toolkit implementation of the MC55.

An URC "Terminate Proactive Command" will be send to the external application in this case, too.
