Plan: I2C support for monitor. Probably I2C is best for debugging
since it's a bus, while SPI is a pipe.
* Use the eusart shift register on the PIC18 for video generation.
This requires communication over a different channel.
* Multiple target debugging for testing other network code.
The simplest way to get multiple targets connected is probably
daisy-chaining them. This would require protocol extensions to
include addressing. The simplest way is to use decrement addressing,
and send replies to #xFF.
Next: implement this. Ok that wasn't too hard.
Now, can I make a cable / bus that attaches to the standard serial
