1.21. Facility lock +CLCK
Execute command is used to lock, unlock or interrogate a MT or a network facility <fac>.
Password is normally needed to do such actions. When querying the status of a network service
(<mode>=2) the response line for 'not active' case (<status>=0) should be returned only if service
is not active for any <class>.
. This command should be abortable when network facilities are set or interrogated.
Call barring facilities are based on GSM/UMTS supplementary services (refer 3GPP TS
22.088 [6]). The interaction of these with other commands based on other GSM/UMTS
supplementary services is described in the GSM/UMTS standard.
Test command returns facility values supported as a compound value.
