Stupid newbie question for 8.0.9

I'm testing conserver 8.0.9 on a Sun system connected to a DEC system
via /dev/ttyb. My conserver.cf file is below. tip to this system works
fine. Whenever I try to connect with console, I get:
  ttyb: permission denied

I'm connecting as root:
  # console -M localhost ttyb

What am I doing wrong?
