I found some initial attempt to implement SetCtrlHandler in the source of Win32::Console. It is commented out in the C part and in the perl part. So i guess the author of the Module failed to get it running and chose to not implement it. Currently it seems to boil down to either attempting to implement the given Code for SetConsoleCtrlHandler myself, or to decouple my output logic from STDOUT, so i can background the process. Sniff. Would have preferred an easier solution.
