I am using a USB<--->serial adapter...when I unplug it from USB the machine reboots itself and leaves the cluster. (This wouldn't be too bad if the battery that stores its settings hadn't died over a decade ago) Anyone else have this problem? Hi Cory I've seen this behaviour from various VAXen including later 4000 models. I now have everything connected to a DECserver 90M with reverse-LAT so, from the computers point of view, there is always a console cable connected. I suspect what is happening is that the computer is treating the cable disconnect as a 'break' which then will drop it to the console prompt. Regards, Mark.
