Hey Ross, I really am not that farmiliar with a great # of microcontrollers,
however I am currently working on a DIC project using a motorola 68hc12. All
versions of the 6812 has a built in SCI (serial Com Interface).. there is a
setup on it in the software registers where you can choose one or two pins
for rx/dx, and many modes there within. I believe the 6811 has the same
setup.. but I'm not too sure there.  Hope that's of help.
