There's a version of the ppbus code that can be integrated into 2.2 at http://www.prism.uvsq.fr/~son/PPBUS. If you want to work with us on this (and we would certainly appreciate that!), the list at ppbus@smith.net.au will reach the relevant parties. > (c) is working on integration of lpt as a proper tty (and get the > if_lp stuff out of lpt.c) to eventually allowing ieee1284 compliant > lptread(). I looked at sio.c and find siopoll() rather confusing... Hopefully the new model will make more sense. If you're looking for some background detail, hit the ppbus list and I'll fill you in. mike
