IMHO, we should drop support for parallel ports. I just cannot imagine
anyone still using parallel ports for AVR programming.
I wouldn't object so much against using parallel ports if it would not
require a custom driver on Windows. Giveio.sys was always a terrible hack,
and the patch guard workaround in the x64 variant is even more. It makes
your system unstable and unsecure, and we should not encourage anyone to use
@Henrik: I understand that you invested quite a bit in getting giveio.sys to
work on an x64 Windows (kudos for that), so I understand you personal point
