Getting Ultrix to answer the phone

[plant at utai.UUCP]

    Hello.  I am a novice System Adminmistrator who is trying to get my
MicroVax to answer the phone.  I am running Version 1.2 of Ultrix-32m.
    In the /etc/ttys file, I set the status to "on modem".  What happens is
the following:
    If I use a modem cable, the modem answers the phone but doesn't give
me the login sequence.
    If I use a null modem cable, the modem doesn't answer the phone.
    If I use a modem cable first, the modem anwers the phone.  Then when I
switch to the null modem cable, I get the login sequence.

    I am using a Hayes SmartModem at the MicroVax end.  Does anyone know
what I should do?  Please respond to:
