Alex,
So you are back to EMC2? :) As I said earlier, a good place to start is the
hal tutorial in the user's manual. See:
http://www.linuxcnc.org/docs/EMC2_User_Manual.pdf
You really need to go through the tutorial to understand how hal works, and
in the process how to configure your system.
Eric, thank you for your detail explanation!
I happened to have a USB from Jon Elson, so I may as well start using
it, though my application
can work just fine with just a parport in an output mode.
Ideally I would like to have already made configuration for a parport
which I could just apply
