disabling login on ttyb

I wish to restrict access to a server. In particular, I don't want
someone to be able to plug a laptop into serial port B and be able
to log in to the server. My understanding is that
/usr/sbin/pmadm -d -p zsmon -s ttyb
will do the trick. I did this to ttya on a server that I know has a
Lightwave console server connected to ttya (its an E250) to test this
out. I still got the login prompt. So apparently this command is
not working or I am doing something wrong. Has anyone successfully
stopped the login process on unused serial ports (without interfering
with the console connection on ttya)?
