public class RCXLNPAddressingPort
extends RCXAbstractPort

RCXLNPAddressingPort provides an interface similar to java.net.Socket Adapted from original code created by the LEGO3 Team at DTU-IAU This version of RCXPort supports the Lego Network protocol (LNP) addressing layer. This supports point-to-point connections. A single byte (for each) specifies the source and destination. Usually the most significant 4-bites specifies the host, and the least significant 4 bits specifies the port. This version only supports a single active port per host. You can use this port for point-to-point communication between specific RCXs, or between a PC and a specific RCX. The LNP Integrity layer is used to ensures that packets are not corrupted, but they are not guarnteed to get through. A three layer protocol stack is used. consising of LNPAdressingHandler, LNPIntegrityHandler and LNPHandler.
