Dave,
We have already tried two different controllers with the same result. We played today with trying all the different modes thinking that possibly there was a documentation error. No Luck! What we see on our RX pin is typically an echo of the TX but with one or two bits changed very definatrely driven by the micro. We have tried several different output characters and the pattern of which bits are switched seems to vary with the value we send but we could not decern a pattern. It is possibe that the wrong pin is mapped out to RX on that port but I can't think of what function would match what we are seeing.

Have you learned any more?
