    I have not done this in many years, but you are right on. The only
    modification I would suggest is to use a terminal server device which
    you can dial into via pots for access to the router consoles as _well_
    as the consoles of machines which support a serial console device.

    It's handy to be able to get to a console prompt or a unix tty and see
    that the network isn't "working" because the border router is not
    passing any bits.

    I think one can still find DECServer 90's (see how long ...) on the used
    market, or equivalent.
