    Now I know that I am able to force the KVM switch to send the power-up signal.
    Unfortunately this causes the "shift" and "screen" LEDs to blink once, whereas
    with the keyboard directly attached to an Alpha the LEDs blink twice. Obviously
    the Rose switch doesn't pass through all the negotiation stuff :-( . It is not
    one of the "dumb pass-through switches".

    So it would be helpful if I could tell OpenVMS to assume an LK411 and suppress
    the negotiation.
