I tried that by adding binding this to a key: (defun signal-hup (proc) (interactive "nProcess: ") (signal-process proc 'SIGHUP)) On a x86_64-w64-mingw32 build, sending SIGHUP to a compilation subprocess results in the emacs abort dialog being shown briefly and then disappearing (without user interaction). That dialog should require pressing a button to dismiss it. AndyM
