tty line discipline on 9820

In article <998 at tness7.UUCP> mechjgh at tness7.UUCP I write:

> "stty 0" will drop the connection, however cntrl-d doesn't.

I thought this was a bug, but it turns out to be a feature.

The port DOES disconnect properly, UNLESS a user process is still
running in the background. (I was running a mail check demon in
the background.)

RTOC says the tty is not closed, so the HUPCL (hang-up-on-close) does
not apply. It may be a feature, but is not consistent with other
machines I have worked with. A quirk I can live with.
