I've had no luck with the local electronics store, so have had to order online. Whilst waiting I noticed that the data sheet mentions
RS-232 operation using internal oscillator
block (no external crystal required)
I can't figure out if this is possible irrespective of using an external crystal. If it is possible to use an internal 32mhz internal oscillator for the comms and the external to run the PIC then could someone advise me how to configure the comms definition bits and registers.

Thanks
