Guys,
12 Mhz crystals arrived today, and using the above now have RS232 coms. Compared to the prototype running with a 20Mhz crystal and the HS_PLL setting, the PIC seems to run a little slower (didn't think you could actually overclock these PICs) - but I can live with that. I much rather have the option of communicating with a PC over a little bit of speed.
