The Radio Interface Unit (RIU) uses the GB2PP protocol to control the radio. When the RIU
has connected to the radio in an Advanced session, all other control units may take control of
the radio any time. For this to happen, only the session needs to be changed from Monitoring
to Advanced or Fixed. Menu 020 (COMLINE SESSION) contains an indication that the radio is
being controlled by an RIU (ADR = 999) in Advanced session.
