49 * Description: FGMultiplay is an FGProtocol object used as the basic
50 * interface for the multiplayer code into FlightGears generic IO
51 * subsystem. It only implements the basic FGProtocol methods: open(),
52 * process() and close(). It does not use Sim Gear's IO channels, as
53 * the MultiplayMgrs creates their own sockets through plib.
55 * It will set up it's direction and rate protocol properties when
56 * created. Subsequent calls to process will prompt the
57 * MultiplayMgr to either send or receive data over the network.
