5.5 AT^SLCK Facility Lock
Description: AT^SLCK provides the “Facility lock” function as defined for the GSM 07.07 command
AT+CLCK. The command can be used to lock, unlock or interrogate a network or ME
<facility>.
AT^SLCK is, in every respect, identical with AT+CLCK, except that the command syntax and
response prefix is “^SLCK” instead of “+CLCK”. For further details please refer to AT+CLCK.
The command can be aborted when network facilities are being set or interrogated.
Syntax: Test Command: AT^SLCK=?
Responses: ^SLCK:list of supported <facility>s, OK
Write Command: AT^SLCK=<facility>, <mode>[, <password>][, <class>]
Responses: if <mode> is not equal 2 and command successful: OK
if <mode>=2 and command successful: ^SLCK: <status>, <class>
[^SLCK: <status>, <class>]
[^SLCK: ...]
OK
If error is related to ME functionality:
ERROR
+CME ERROR: <err>
Notes:
This command is PIN protected. This command is available after PIN2 authentication. See +CPIN2.
In airplane mode, not all described functions are available. For example, the test or read command is usable, the
write or execute command may not. Furthermore, only some of the listed parameters can be changed in airplane
mode. A typical example is AT^SCFG that controls different features.
Specifically, in the airplane mode the write command version for the network related <facility> (AO, OI, OX, AI,
IR, AB, AG and AC) is not supported. For remaining facilities the command is fully functional then.
