Detailed Description

Contains implementations for KdComDispatcher::KdSendPacket() and KdComDispatcher::KdReceivePacket() functions that are executed on host side.

This class contains host-side implementations of KdSendPacket() and KdReceivePacket() functions. These methods are called by KdRpcDispatcher class via IKdComDispatcher interface.

Remarks:
See the kdxxx.h file reference for info about KdSendPacket() and KdReceivePacket().
