Ack!  How could I miss that?

Thanks Mr. Tellason, I hereby "un-poo".  

A digital in would do nicely, especially if the board has something that does the UART
thing in hardware or if the MPU/CPU/MCU has a built in general purpose UART.  I don't like
to use a processor to do the serial bit shift thing, I prefer a real UART so that the
CPU/MPU/MCU isn't burdened with that.
