Sorry for all the confusion.
I'm a hardware based software guy:-)
The easiest way to bypass this is the add an "alias" -- another property that is
the inverted state of the PIO pin. What should it be called?
Maybe another idea: something like --dont-convert, --dont-negate or
--raw-rw to configure?
And do not convert input/output with this option - just raw values like in
documentation of chips.

Subject: [Owfs-developers] 1=conducting ?
Hello,
I know that now is too late for 'idea' correction, but in 'real'
electronic world all 'switches' like DSxxxx with open drain/collector
and second pin grounded, have clearly defined conducted state as 0
because this IS a 0 state in CMOS and TTL logic.
I saw on the list also some problems related to this strange assumption
(for eg. thread about DS2413).
In DS2405 this is reasonable because Dallas really made io pin with
inverter and started 'inverting things', but in DS2413 or DS2408 it isn't.
Maybe this issue should be better documented? Some warnings to electronic
guys? :-)
Despite of this - good work!
