Oh oh......are you using an 823 or 850? Sorry about this, you will
have to change the code. Someday, I have to finish up a better UART
driver. You are the first person I know that is trying to use this
as a UART. SMC2 is the first thing to disappear when using the parts
for other data communication protocols or interfaces, so custom
software tends to assign these for other purposes. I seldom see anything
but SMC1 used for a UART, so making the driver better hasn't been
high on the list......
