Hi,
I tried this: http://owfs.sourceforge.net/WRT54G.html and it doesn't
work for me.
It looks really weird how the author connected the DS2480B, which runs
at 5V directly to the UART, which provides only 3.3V. I think this would
need some level-shifting.
The datasheet also says the POL-Pin (Pin6) has to be tied to +5V if
directly connected to the UART.
I made a small schematic with some resistors as level shifters:

think I like it. It's said that doing level shifting is very power hungry.
Any better ideas?
