I'm trying to use the parallel port get an external trigger to wake up
my software. When I use subdevice 3, and prepare a command with
scan_begin_src=TRIG_EXT (as in ledclock.c), I get an error:
comedi_command: Command not supported
It looks like I have the comedi_parport driver properly setup. info reports
the following:
