tty00   "/usr/libexec/uugetty std.38400" vt220 on secure rtscts

   "secure" is so I can su root, and "rtscts" is pretty much the standard. 
   You would need to make a special cable to use "mdmbuf."

Actually, "secure" is so that a direct root login is allowed.  One can
su root even without a secure line if groups are set right.

Cheers,
