I want to type: ln -s /dev/ttyS2 /dev/modem but mistyped to: ln -s /dev/ttys2 /dev/modem I want to break this link,but forget the cmd.Now whenever ls -l /dev/modem,always -->/dev/ttys2.I want it -->/dev/ttyS2. I haven't find the cmd in man.Any idea? Bill [ February 11, 2002: Message edited by: Bill Koo ]
