With newbus, this hack is no >longer possible (it was never correct anyway; it broke printing). Or by statically configuring SLIP (which forced tty = net), or maybe by dynamically configuring PPP. The tty = net hack went away with old-bus, so SLIP is broken in much the same way as PLIP. >The problem with PLIP is that it tries to do splnet stuff in at >spltty.

Possible quick fix (hack): change all the spltty()'s in lpt.c to splnet()'s. lpt isn't a tty driver; it just abuses spltty(). Abusing splnet() instead should work OK for lpt and fix if_plip.
