The default diagnostic output channel I believe is the first serial port, 
not the screen. Connect your serial port to your host using a null modem 
cable at 38400-8-N-1, or edit the CDL configuration for the PC HAL to use 
the "screen" diagnostic channel by default. i.e. set the default 
debug/console channel to 2. (0,1 are first and second serial ports).
