You enable it in the ttys file with "... on secure modem shared ...".
You verify it with "file /dev/tty??", it says "modem control on" or
"modem control off".

So now, you have the shared flag for use of the line for both outgoing
and incoming calls.
-------------------------------
If you connect to the modem with cu, do sth eg. dial out and then quit the
cu session --> the modem control is off !!
-------------------------------

Now you have to edit ttys and send init a kill -HUP a dozen times `til you 
finally managed it, to enable modem control again - until the next session
with cu.

What I wanna know is WHY is it so complicated, HOW can I work around this.
It`s also the same w/o the shared flag, that means turn getty on and off
for incoming and outgoing connections.

I really hate it; pls tell me that I`m doing sth wrong (and what) instead of
"you have to live with it, it`s the ugly tty driver".

(This occurs under Ultrix 3.1, 4.0 and 4.1 on at least MV2000, MV3900,
DSys3100 and DSys5100 at the local 25 pin serial port.)

Pls email, I`ll summarize if there is interest.

Thank you very much.

Dietmar
