It is acting more and more like one all the time :-) That is the point of all of this - to not get phony error messages from the devices when performing normal functions (such as RUN during DETACH or Logoff). We have made a lot of progress from streaming unsolicited interrupts, to reflecting a state that caused 11 lines of error message, to one that only triggered 6 lines, to this single message. The best would be no message at logoff and only a successful detach message if the user detached the device. Currently, the user who detaches the device does get the successful detach message AND the operator gets the HCPERP2215A. So we are halfway there.
What manual do you use to determine there is a special Unit Check? Is it online where I can see it?
