> 16.1 | AT^SSTA SAT Interface Activation

> The AT^SSTA write command activates the AT command interface of the SIM Application Toolkit in the TC65 and needs to be issued after every restart. 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) are executed without activating Remote-SAT.
> The read command can be used to request the current operating status and the used alphabet of the Remote-SAT interface.
> Syntax

> Test Command AT^SSTA=?
> Response(s)
> ^SSTA:(list of supported <state>s), (list of supported <Alphabet>s)
> OK

> Read Command AT^SSTA?
> Response(s)
> ^SSTA: <state>, <Alphabet>, <allowedInstance>, <SatProfile>
> OK

> Write Command AT^SSTA=<mode>[, <Alphabet>]
> Response(s)
> OK

> Parameter Description

> <state>(num)

> TC65 Remote-SAT interface states
> 0
> RESET
> 1
> OFF
> 2
> IDLE
> 3
> PAC
> 4
> WAIT

> <Alphabet>(num)

> Parameter is stored non-volatile and takes effect after next restart of the ME.
> 0(D)
> GSM character set
> Input of a character requests one byte, e.g. "Y".
> 1
> UCS2
> To display the 16 bit value of characters represented in UCS2 alphabet a 4 byte string is required, e.g. "0059" is coding the character "Y". For details please refer to ISO/IEC 10646.

> <allowedInstance>(num)

> 0
> SAT is already used on another instance (logical channel in case of the multiplex protocol). Only test and read commands can be used.
> 1
> SAT may be started on this instance via the write version of this command.

> <SatProfile>(str)

> SAT profile according to GSM 11.14 [27]
> The profile tells the SIM Application which features (e.g. proactive commands) are supported by the SIM Application Toolkit implementation of the TC65.

> <mode>(num)

> 1
> Activate Remote-SAT
