The only explanation I could find is that if you send 2 (or more) breaks to a program, the first kills the program and the following the spm (don't forget that spm is listening on sio1 !). I dumped /sys/spm/spm and found an switch in it, '-no_stdin[]', that should prevent the spm from listening on /dev/sio.spm, just I don't know how give the option to the spm. Another possibility is to delete the /dev/sio.spm link and create an empty file with that name; then the spm will not go out on sio1 and the break problem should disappear. We used a different solution: we put a switch on the terminal output wire ! If you want to type something on the terminal, you have to switch it on before; hopefully this will remind people that extra care is needed. Achille Petrilli, Cray Operations
