        $ dmesg | grep lpt
        lpt0 at isa0 port 0x378-0x37b irq 7

It's so odd that I switched kernels twice just to make sure it was no
fluke.


BTW: ps(1) told me that every /dev/lpt0 writer hangs in lptwrit, which
I assume is the truncated version of `lptwrite2' somewhere in lpt.c.

Also interesting: The LED on the printer that indicates incoming jobs,
turns on as soon as a writer enters lptwrite()/lptwrite2.
