Subject: Still debugging why open("/dev/lpt0"...) hangs

lpt0 is hanging up when it tries to request the ppbus (line 478 of lpt.c). I'm guessing that if_plip.c has requested it and not released it, which apparently happens when there's been an ioctl on the plip. There's no plausible reason why this should happen. What can I call in lpioctl (if_plip.c line 302) to print out some identifying information about the process doing the ioctl? Or is there a better list somewhere to ask this question? -- George Mitchell
