[vox-tech] Receiving an interrupt from a parallel port using xlib

[Mitch Patenaude]

I'm not aware of any special x library or gnome abstractions.

In general.. interfacing with the parallel part involves reading, 
writing, and using ioctl calls on the character special device 
associated with it... usually /dev/lp0

Actually hooking into the interrupt would involve writing or modifying 
the device driver, but there are certainly ways to check status bits 
without doing that.
