 *	Copyright (c) 1993 - 1995 by DataBeam Corporation, Lexington, KY
 *
 *	Abstract:
 *		This is the interface file for the Connection class.  Instances of
 *		this class are used to connect CommandTarget objects within the local
 *		provider to CommandTarget objects in a remote provider.  This class
 *		inherits from CommandTarget, allowing it to communicate with other
 *		CommandTarget classes using their common MCS command language.
 *
 *		This class can be thought of as providing a Remote Procedure Call (RPC)
 *		facility between CommandTarget objects.  When an MCS command is sent
 *		to a Connection object, it encodes the command as a T.125 Protocol
 *		Data Unit (PDU) and sends it to a remote provider via the transport
 *		services provided by a TransportInterface object.  At the remote side
 *		The PDU is received by a Connection object who decodes the PDU, and
 *		issues the equivalent MCS command to the CommandTarget object that it is
 *		attached to.  The fact that the call crossed a transport connection
 *		in route to its destination is completely transparent to the object
 *		that initiated the command sequence.
 *
 *		The primary responsibility of this class is to convert MCS commands
 *		to T.125 PDUs and back again (as described above).  This class overrides
 *		all of the commands that are defined in class CommandTarget.
 *
 *		A secondary responsibility of this class is to provide flow control
 *		to and from the transport layer.  To do this is keeps a queue of PDUs
 *		that need to be transmitted (actually it keeps 4 queues, one for each
 *		data priority).  During each MCS heartbeat, all Connection objects are
 *		given the opportunity to flush PDUs from the queues.  If the transport
 *		layer returns an error, the PDU in question will be re-tried during
 *		the next heartbeat.  For data coming from the transport layer, this
 *		class provides code to allocate memory.  If an allocation fails, then
 *		an error will be returned to the transport layer, effectively telling
 *		it that it needs to retry that data indication during the next
 *		heartbeat.
 *
 *	Caveats:
 *		None.

 *		James P. Galvin, Jr.
