      DECnet (NCP) has a TRIGGER command that sends a special MOP message

that are located in remote locations where there   s no operator around to
conveniently flip the RESTART toggle.

    The problem is that it doesn   t seem like there are many PDP-11 or VAX
communications interfaces that actually implement this.   The DMR and DMC
appear to, but as far as I can find those are the only ones.   In
particular there don   t appear to be any QBUS interfaces that can do
it.     Have I missed any?   Has anybody ever done this?   What interface
did you use?

I thought the DELQA did? I don't think the DEQNA did, however.
Also, the DEUNA and DELUA handles it, as far as I know.
