This software I use for my commercial programmer (no one else could drive it
except this and the original one that was provided along with the
programmer).
http://people.freenet.de/dl4yhf/winpicpr.html

On that site and in the help files of the software you can also find
parallel port programmers (a very simple one and one that works better with
newer PICs).
