Here is a bit banging routine: http://www.dontronics.com/psbpix/serin1.html

Your job will be much simpler if you have a hardware UART on the PIC.

Here is code/tutorial for using hardware UART:

Hope this helps
Good luck!

Thanks Neil and Herbert for the reply. I think I will try serially just
because it has power and sounds more convenient and neater. The data rate is
really not important to me at all. I just want to confirm that I can power a
pic off the serial port, I always though a mouse was a fairly passive device
and so very little current could be drawn? Also you wouldn't perhaps know of
a good place to get a code example of a pic/serial port communication (RS232
I guess)?

Thanks once again.
Jason
