Hi, I have a board we've developed for a class, and we talk to it using
EPP.
It is possible to talk to it by directly writing the the EPP registers
[0x378 +3 and +4 for address and data], but you need to be root.
I was trying to do this using the ppdev driver, thinking it would best to
do this simple communication in user-space. I was having great trouble
trying to get this to work, only to dig into the ppdev.c code to find it
with comments saying "this hasn't been tested yet", and it seemingly is
doing it in software instead of hardware!
I then looked at kernel 2.3.99-pre3 thinking it might have more mature
support, and it looks like all references to EPP have been stripped out of
ppdev...
so the question is, can EPP be done with ppdev?
