RF200 UART faster than 115200

[jcwoltz]

I thought I already posted this, but I don't see it. Here is a little script that will peek the various registers on the ATMEGA128RFA1/RF200/SM200 for the UART and display them. This script also has functions to change the UART to a speed faster that 115200. In my testing the RF200 can transfer at 1M, but not sustain the transfer rate for large amounts of data.
