Yes.  (But not here.)

It will run.  Add

	pseudo-device	sl	2	# or however many you need

to your configuration file, run /etc/config, make depend, make.
Boot the new vmunix, make sure characters sent on ttyXX show up
at the other machine, and run

	slattach ttyXX 1200 &		# or whatever speed

If you need a modem dialled, write a program to do that, then run
slattach.  If the line drops, slattach should die with a SIGHUP,
and you can automatically redial.

There are, however, a few bugs in the code as distributed.  In
particular, if you get low on clists, the SL interfaces may lock
up.  I have no official fix yet (low priority).
