Thanks, I already worked with 1-wire devices (DS18s20) with digitemp http://www.digitemp.com/ but it was only to display outdoor temperature and build charts with GD. But I never built an application to drive something from Linux (e.g. from serial or // port).
I'll investigate your hardware tracks.
