+CLCK, Facility Lock
This command locks, unlocks or interrogates a G24 or a network facility <fac> (any kind of call
barring program). A password is mandatory for performing locking and unlocking actions, but
not for querying. The features of the G24 that are affected by this are the keypad power-up
operation and fixed dialing list. When querying the status of a single call barring program
<mode>=2, the <status> for each call type will be returned.
For <fac>="SC", SIM Card PIN setting and for <fac>="FD", SIM Fixed Dialing memory setting,
the <class> is irrelevant (For more information about <class>, refer to the following table shows
the +CLCK parameters.). The <passwd> for "SC" is SIM PIN, and for "FD" it is SIM PIN2.
