since the comedi support in ocl moved to comedi-0.8 i was updating our
robots hardware components, and apparently the positionSet() on a
ComediEncoder has no effect. I know that the ComediEncoder was one of
the devices that changed most between comedi-0.7.x and comedi-0.8, so
probably something went wrong there.
I'll try to find out why it does not work anymore. I'm just reporting
that there is probably something broken in the ComediEncoder code.
