/*
 * Emulates the RCX Remote control
 *
 * @author Lawrie Griffiths <lawrie.griffiths@ntlworld.com>
 * 
 * Bugs:
 *   Beep does not work twice in a row with standard RCX firmware.
 *   Commands only work every other time with RCX leJOS RemoteControlTest
 *   example (due to the RCX leJOS Remote Control system not
 *   handling the 0x08 toggle bit in RCX opcodes).
