What disagnostic pages does this thing support? Can you do a receive diagnostic on page 0 to find out? I suspect a lot of embedded enclosure services are simple and support page 7 only. If it really refuses all diagnostic page requests (which would be a gross standards violation), then it should probably be blacklisted by inquiry string as unusable. James
