Reductio ad absurdam; which, btw, is never a valid argument for, or against. P.S. I once wrote code to change line idle code on Multi-drop X.25 from 7E to FF, because AT&T ignored DTR and had all their MJUs run wide open, thereby destroying a NRZI multidrop 56kbps digital circuit, so the above scenario is not fictitious. Needless to say, pulling the plug was not an option.
