Using WD40 on a Remote Services Consoles

Ok, I'm completely baffled. Is there some sort of conspiracy afoot to not discuss how the DEC remote services console works or is used? I know that there are ex-DEC field service types here and certainly ex-Digits who should know the basics. And yet at least three times over the last 2 years theses questions have come up and been left hanging with absolutely no information. Whazzup wit' dat? I happen to have a use for mine that is exactly what was intended, I've got a VAX 4000/300 sitting at my office that I'd like to be able to dial into the console and reset and reboot. I don't have a spare serial port on a PC to use and it would be "cool" to do it with this piece of vintage gear that was designed to do this. Yes, I know these things were originally DEC proprietary and secret stuff but heck DEC is dead. We've got to keep this information alive, not let Compaq take it to the grave with them. --Chuck
