Lightbulb linux device driver & parallel port

I'm trying to implement a program, which is need of a device driver,that works on parallel port. During my searches in internet I came across the best documentation about this topic, which can be foun dn the following address:

However, since I don't have any exprience in writing device driver, I couldn't manage to do the things, which I would like to get over.

What I want to implement is very simple. When the value on one of the pins over the parallel port is changed, an interrupt or a signal is wanted to be generated, which will cause a program in user space to be interrupted.

System Specifications on my computer:
OS: Redhat 7.3
Kernel Version: 2.4.18

I would be very happy if anyone could help me.
