     33  * This class provides a "Sequenced" ACK/Retry approach to packet				*
     34  * transmission.  It waits until the last packet has been ACK'd before		*
     35  * sending another packet.  Thus, it guarantees order of delivery of			*
     36  * packets, but its performance will be slower than the Non-Sequenced		*
     37  * approach.																					*
     38  *																									*
     39  *	A derived class must provide:															*
     40  * - Init: Initialization of any hardware-specific values.						*
     41  * - Send: a hardware-dependent send routine.										*
