>Description:
The FreeBSD port cad/brlcad makes use of sgtty, which is a bad thing,
because sgtty only works when you use COMPAT_43TTY in your kernel
configuration. brlcad already has code laying around for termios, but is
never enabled. We can just enable it, but we need to fix it up slightly,
because FreeBSD's tab expansion flag is called OXTABS, instead of TAB3.
