/* This file defines the message format for communication between TOSSIM
 * and TinyViz (the TOSSIM GUI). Communication is bidirectional using
 * two sockets: EVENT_PORT is used to send events from TOSSIM to 
 * TinyViz; COMMAND_PORT is used to inject commands from TinyViz
 * into TOSSIM. Every event sent by TOSSIM on EVENT_PORT is 
 * acknowledged by a single-byte ACK before the simulator proceeds. This 
 * allows the GUI to throttle the execution speed of the simulator by 
 * delaying the ACK. Commands sent into TOSSIM by the GUI are not 
 * acknowledged.
 *
 * * NOTE NOTE NOTE NOTE NOTE NOTE NOTE *
 * If you wish to add new command or event types here, there are several 
 * other things you must do. For details, see the README file in 
 * tools/java/net/tinyos/sim.
