Matt, thank you very much for sharing this information. We'll definitely 
take another look.

So can you say whether the UART interface is (or can be made to be) 
"transparent"? In other words, can it work as a serial cable replacement 
"out of the box", without the need to send it configuration commands from 
the micro?
