- I have also noticed that lpdev ceased to work after applying Kay's net
- patches to the kernel. Apparently, there is interference with the PLIP
- driver, which is not too surprising since each one wants to reprogram
- the MFP interrupt source 0 for its own use. You could probably fix the
- problem by commenting out the PLIP code (haven't tested); more simply,
- just send anything to /dev/centr, after that /dev/lp should work just
- fine. (I haven't an explanation for this, but I guess that PLIP fiddles
- with the active edge register, and that -one- Centronics interrupt is
- enough to put things back in order.)
