8.2.1Description
Locks, unlocks or interrogates an MT or a network facility <fac>. A password is normally needed to do such
actions. When querying the status of a network service (<mode>=2) the information text response for "not
active" case (<status>=0) is returned only if the service is not active for any <class>. Instead when querying
the status of a network service (<mode>=2) asking for a specific <class>, the DUT sends a generic request.
The command can be aborted if network facilities are set or interrogated.
For <fac> "PN", "PU", "PP", "PC" and "PS" only <mode>=0 and <mode>=2 (unlock and query status) are
always supported.
For <fac> "PN", "PU", "PP", "PC" and "PS" <mode>=1 (lock status) is supported only if proper re-activation
characteristic is enabled during personalization.
