Looking at the 4.3Tahoe (which particular 4.3 version

I find it hard (without further digging) to figure out how it gets from where
it should discover carrier has gone away (in dzrint(), from dztimer()) to the
rest of the system; they have added some linesw[] thing I don't know about.
Thanks for digging Noel. Strangely, I've just installed a vanilla 4.2BSD
and it does the same thing.
The 4.3BSD dz(4) manual does say:
FILES
/dev/tty[0-9][0-9]
/dev/ttyd[0-9a-f] dialups
but /dev/MAKEDEV doesn't seem to have a way to make /dev/ttyd*
