Class RCXAbstractPort

java.lang.Object
  extended by lejos.rcxcomm.RCXAbstractPort
Direct Known Subclasses:
RCXPort

public abstract class RCXAbstractPort
extends Object

RCXAbstractPort provides an interface similar to java.net.Socket Adapted from original code created by the LEGO3 Team at DTU-IAU RCXAbstractPort implements input and output stream handling and input buffering. It uses a packet handler for sending and receivng packets. This version is abstract because it has no packet handler defined. Specific versions of RCXAbstractPort override the constructor and set up the packet handler to use a specific protocol stack.
