14.3 AT^SCKS Query SIM and Chip Card Holder Status
This command controls the SIM connection presentation mode and queries the connection status of the SIM and
the card holder tray of the MC55.
Syntax
Unsolicited Result Code
^SCKS: <SimStatus>
During startup, and if the MC55's SIM connection status has changed an unsolicited result code (URC) is issued.
Command Description
The read command returns the URC presentation mode and the status of the SIM card connection.
The write command enables or disables the presentation of URCs to report whether or not the SIM card is con-
nected.
If the ME is powered down or reset (AT+CFUN or AT^SMSO) the current presentation mode setting <mode> will
not be retained. Therefore the setting <mode>=1 needs to be restored after power on the MC55 or may be saved
in the user profile (AT&W).
