[HECnet] Which DECnet interfaces support remote, unattended, booting?

DECnet (NCP) has a TRIGGER command that sends a special MOP message to a remote machine, and that s supposed to force the machine to do a hard reset and the reboot, presumably via DECnet. It s for machines 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? Thanks, Bob
