Re: PIC12C508A-based remote - some remarks

I believe the '508A will work out OK. The open-drain is not a problem, as it
can be emulated by tri-stating the output (that's what I'm doing). The
oscillator spec does go outside the limits required for async comms, but, in
practice, seems to be better than the spec. I've included baud rate
adjustment in case anyone (including me) runs into problems when burning a
different device than my development part, which is comfortably within spec.
