Unfortunately a resonator will eat up 2 valuable pins, and a crystal oscillator (using 1 pin) is too pricey for the project. So I'll have to bump up to a 16F627 or something, and that is $$ too. Argh!
The 12F615 cost 2/3 what the 12F675 costs and has a 4/8MHz internal oscillator. I've used it at 9600 but have never had the need to try 19200. It's a fairly new chip so the accuracy of the internal oscillator may be better than that of older PICs.
