Yet it didn't. Therefore it was very confused about its own state and as a safety measure it told its probes "hang on a minute while I figure out my own situation" :-) We designed the controller-probe protocol so that it can handle case such as this; that is, the probes will try reconnecting, and in really bad cases the system drives them to a different controller. In the meantime they execute what they were asked and store results. > J. > > Anyway : probe is ok for 5 hours, 42 minutes Good, good! Cheers, Robert
