Shared Terminal Under Ultrix 1.2 (bsd 4.3)

[Hurf Sheldon]

 In the documentation for the /etc/ttys file there is an option
of declaring a tty shared. Does that allow getty to sit active on
a port and allow using the port as an out device as well? 
  What I want to accomplish is to have a dialout line also be a dial
in line with login prompt, etc. Unfortunately it isn't obvious to
me how to do it. My attempts have resulted in the login prompt
looping back in on me as any time anything comes in the port getty
says 'login'. Is there an elegant way or must one write a script to 
alter ttys, kill the sucker, use it , reverse the process etc?

I know I'm slow, but I try to be smooth to make up for it.
