I have modified the picprg2.2 software so it could easily adapted to supp=
ort more devices, and it has an automatic paralel port interrupt configur=
ation (looking in=20
/proc/ioports). I have mail to Brian Lane (first programmer of picprg), a=
nd he told me he wants to make the new release with GPL. The problem is t=
hat I can not test=20
what I made. I mailed the program I made to Brian several months ago, and=
 he told me he will try it, but he doesn't do it at the moment.
If someone wants to give it a try, please, mail me and I will send you th=
e software.
