Should we be unable to do this? If so, >should we be alert for it to stop working when someone "fixes" it? As long as UUCP never transmits one of the sequences RETURN escchar . RETURN escchar Meta-DEL RETURN escchar escchar (where escchar is the character set by -e, default `~') it will continue to work. Obviously, these three sequences are statistically unlikely: P=3/256^3 in uniformly random data, or about .000018%. You should be able to manufacture a file that will reliably break the connection, however, and Murphy dictates that your boss will do it. -- In-Real-Life: Chris Torek, Univ of MD Comp Sci Dept (+1 301 454 7163) Domain: chris@mimsy.umd.edu Path: uunet!mimsy!chris
