Break serial lines with optical isolators. Yes, fiber will solve ground loop problems. And this smells like a ground loop issue. But at this juncture, I don't have enough specifics to recommend ma$$ive changes. > Cut the ground wire in your power cords but ground the equipment directly > to a metal frame.

I don't recall mention of RS-232,. but yes, this is the classic example of ground loops. -- A host is a host from coast to [email protected] & no one will talk to a host that's close........[v].(301) 56-LINUX Unless the host (that isn't close).........................pob 1433 is busy, hung or dead....................................20915-1433
