/* 
   Remote Commander - IR Version
   Designed and implemented by Benjamin Bostwick (bb46@andrew.cmu.edu)
*/

Remote Commander has been tested on Win95, no support is provided for Win98

To Use IR Commander:

1. Start Windows IR Monitor

2. Start Remote Commander PC and set the port to the virtual IR serial port number

3. Start IRCommander on the Pilot

4. Press the "Start IR" button on the Pilot

5. The IR monitor should indicate that a connection has been initiated.  Once initial
handshaking has been completed, the Pilot will return to the Remote Commander screen
and IR communication is active.

6. When finished with the IR commander, press the "Start IR" button again, then press the
exit button or switch apps.  If you exit without pressing the "Start IR" button, IR 
functions don't get shut down properly and you may have to restart both the PC and Pilot
in order to get IR communication to work properly again.


WARNING:  The IR operation is very delicate.  I'm not exactly sure why, but the IR 
communication is very slow.  I implemented a crude buffering scheme, but it still gets
backed up quite often.  If a lot of data is being sent (i.e. scribbling on the pilot) 
the IRCommander will crash.
