Re: INT_TRIG for scans...

I wont run simultaneously commands, but various in sequence:

... some configurations...
comedi_command_test(dev_comedi, &cmd);
comedi_command(dev_comedi, &cmd);

...
some code
....
(at this point, I'm sure that the previous command have been terminated)

...another configurations...
comedi_command_test(dev_comedi, &cmd);
comedi_command(dev_comedi, &cmd);
...

why only the first command executes?
