I understood this. But Comedi over RTAI works today (haven't tried that
myself, but I have seen some projects using this combination). It will
not work tomorrow, but I need a solution yesterday :-)

I understood this too. But to me it was looking like there has been a
functional Comedi port to RTDM in the past, and that Analogy is more an
effort to clean up the Comedi implementation. I misunderstood this
second part.

PS: I'm sorry if some of my email sounded a bit harsh, but I'm a little
bit frustrated by the situation. I'm new to this kind of applications,
I'm a physicist more than a programmer. Xenomai works great, Comedi has
some rough edges, but finally I made it to work as I need. It is
disappointing to find out that those two do not work together and that I
have to rethink my application.

Thanks for the clarifications. Cheers,
