I was so sure this was discussed before that I've spend the past two
hours searching the archives at iversoft and piclist.com (search not
working there).

I am looking for a nifty idea to monitor a single wire bus. The bus is
floating when idle (no pullup/downs). So I can not just set the PIC I/O
to input and monitor it. The pic must read the tristate as neither a
high or a low. IOW, the PIC waits for a high or low.
This is a hobby project where I want to connect up several PICs on a
single wire. (I know about I2C and SPI, but that will defeat the whole
point).

Thanks
Quentin
