Slight correction to the wording of my original post. It should have read 12Mhz Crystal clock and not 10, although I did have it right in my coding as far as the DEFINE OSC 12 was correct. I could not work out why my calculations were wrong when compared to the results from Steve's excellent calculator (link shown below). A stupid mistake, but after correcting things, it still does not make any difference to the problem I am having. I have tried changing all the Parameters in Serial Communicator to all the different combinations of settings available and still no joy.
