Hi Frank, it seems to work now.

root_at_einstein:~/CVS/comedilib-counter-anoncvs/build-gcc-4.0/demo #
   ./gpct_pulse_generator -s 2 && echo succes
Generating pulse train on subdevice 2.
Period = 1000000 ns.
Up Time = 500000 ns.
Down Time = 500000 ns.
succes

   ./inp -s 2 -c 0

root_at_einstein:~/CVS/comedilib-counter-anoncvs/build-gcc-4.0/demo #
   ./inp -s 2 -c 0

I don't see a signal appearing on a scope yet, but I guess this has
something to do with the following comment in the head of
gpct_pulse_generator.c?

  * The example assumes the board has already been configured to
  * route the output signal of the counter to an appropriate
  * location (you may need to route it to a PFI output line
  * for example).

Klaas
