Operation
B - NOT SELECTED
A sub-status of CONNECTED in which no HSMS session has been established or
any previously established HSMS sessions have ended.
C - SELECTED
A sub-status of CONNECTED in which at least one HSMS session has been
established. This is the normal "operating" status of HSMS: data messages may
be exchanged in this status.
The specification of a required TCP Application Program Interface (API) for use in
implementations is outside the scope of HSMS. An HSMS implementation may use
any TCP/IP API sockets, TLI (Transport Layer Interface), etc.
