-  Specifically designed for the xplain board, other uses could be made by furkling through the code
-  and replacing the port and pin assignments. Also relies on and external interupt to detect the low
-  level of the start bit, in this case INT0.
-  Always configured to 9600baud. Can be changed by setting the BITLENGTH define to F_CPU/(desired baud)
-  code may need optimising when getting any faster to sample the bit in the correct place. No 
-  compensation has been made for the response time of the int routine.
