Dave, thanks for the inputs. I could not have designed the actual hardware interface to the mains without your invaluable pointers to powerline carrier articles.

Are you suggesting that X10 signals would be better generated in PBP without using the XOUT macro? My X10 transmitter is a very basic one, so the micro dim/brights are not an issue.

I would have loved to have some extended commands though.

Again, a heartfelt thanks.
