Though I have worked with real 3270's in the past, I am no expert on the CUT or DFT protocols. However, it would not surprise me at all if, for a 3278, that information is provided by the controller -- but not as part of the data stream that the host computer sees. I found these documents, but they don't address that status line, because they are for the older 3271/3272 controllers. http://www.bitsavers.org/pdf/ibm/3270/3271-3272_to_Device_Interface_Spec_May74.pdf http://www.bitsavers.org/pdf/ibm/3270/fe/ANR-specification-1975.pdf JRJ
