And mine is mostly defunct

The protocol is

	0xFF [padding]
Then either

	0xFE A B


	0xFF A B C D

C/D are the high bits of a 14 bit value and need not be sent if they
didnt change at all. C/D cannot be 0xFE/FF but A/B can, which can mean
it takes a few samples to sync.

	X low is A
	Y low is B
	Xhigh is C
	Yhigh is D

All this should be at 19200 8N1
