Yeah, it's a UART. But I assumed you wrote data to a register, then wrote 
data to a different register to strobe the data out, etc. So I figured the 
first register was just a temporary buffer that would hold it's contents 
until replaced by data in the opposite direction. My bad.

I'll look up the test loopback adapter wiring.
