People,

I have comedi installed on a Fedora 3 machine.  I think I'm running
comedi 0.7.73 with RTAI installed.  I have the National Instruments
hardware installed with ni_pcimio connected through /dev/comedi0.  I
also have the National Instruments external hardware connected with
thermocouples attached to channels 0 and 1.

The main problem that I'm seeing is that I can access the thermocouples
on channel 0 and 1, and while the conversion algorithms are doubtful,
that doesn't bother me too much as long as the A/D output is reliable.
At this point I don't have any reason to doubt the A/D output.  The main
problem arises when I attempt to reach the ice-point compensation
outputs on channels 8 and 9; at which point I seem to get back the
thermocouple readings again.

Can anyone give me some guidance here?

    Harold Skank
