two-way communication through the same port under SunOs 4.0?

According to my SunOs 4.0 manuals, as of this release you're supposed to
be able to run a getty on ttya to enable logins, and simultaneously hook
an outgoing modem onto the same hardware port, calling it /dev/cua0.
Whichever application (login or, eg, tip) grabs the port first is supposed
to lock it to other applications. I've tried this, and I think I have all
my gettytab, ttytab and /etc/remote entries correct, but the getty on ttya
(or ttyd0, or ttym0, no matter how I try it) renders /dev/cua0 busy for
outgoing calls. According to my manual, this isn't supposed to happen.
This is on a 386i, but a colleague trying the identical things on a 3-160
running 4.0 exhibits the identical symptoms.
Has anyone gotten it to work, or is it a known bug, or what?
