Public Function ListenSpecific( _
   ByVal Port As Long, _
   ByVal Address As String _
) As Boolean

More than one port may be active simultaneously.  The listening sockets are all closed when the control is de-activated.
Closing a “listening” socket has no effect on currently active associations that connected via that socket.
Port is specified as a long integer, to avoid ambiguities in the range 8000-FFFF.
If the specific option is used, then address must be either in dotted form, or a resolvable name.
