Serial Question + General Review

[skimask]

What I have to ask is - will my serial work in that configuration (tx + rx -> single pin)?

It can work just fine using serial communications over a single pin.......provided you use the software serial commmands (i.e. SERIN/SERIN2/SEROUT/SEROUT2/DEBUGIN/DEBUG, etc.) and not the hardware or it's commands (i.e. HSERIN/HSERIN2/HSEROUT/HSEROUT2). PBP should/will automatically set the pin to input and/or output as required...should that is.

I'd rather not use the software equiv in this case as it's quite a busy little chip and I'd really like to have the interrupt and buffering. I know I can use interrupts on portb, but portb is quite busy - especially with constantly turning the WPU on and off
