The easy way to accomplish the same thing is to change std.115200 to
3wire.115200 (and then do 'init q').

Hi Ian,
Changing the line following line from std.115200 to 3wire.115200 worked.
Can you explain the why? I am not entirely sure of the difference between
3wire and std there.

ttyu0   "/usr/libexec/getty 3wire.115200" vt100   on          secure

Thanks,
- Jordan
