Several bits of useless trivia I've collected which you may find useful 
someday:

1) If you're going to do kernel development get a VAX 4K90 or better.

2) The "second" serial port on the 4K90 is /dev/tty02 if you want to hook
    it to another VAX's console (device under test) you need the following
    line in /etc/remote:
	 vax:dv=/dev/tty02:br#9600:pa=none:dc:

3) To use tip as a non-super user you should:
	a) put yourself in the 'dialer' group
	b) change the ownership of the tty port its using to
		chown uucp:dialer /dev/tty02
		chmod 600 /dev/tty02

Once you have completed steps 2 and 3 (and connected the ports) you can type:
	tip vax
and it will connect you to the console port of the VAX under test.

The serial ports on the VAX 4000/VLC, 4000/60, and 4000/90 show up as 
tty00, 01, 02, and 03.

The serial ports on the DHV11 and CXY08 show up as ttyS0, S1, ... S7.

If you don't set the tty 'on' in /etc/ttys getty won't run on it.

Connecting two ttys that have getty running on them together is a bad thing.

You can use uucp with two back to back serial ports to copy files if the 
network doesn't work.
