This seems like a wrong fix. A real 3-wire serial console doesn't have DCD and DSR wired on. Why isn't the right fix here having the user with this problem to do "stty -f /dev/ttyu0.lock clocal", maybe in rc.local? Hmmm, or maybe it would be right for getty to do the equivelent when it sees a 3wire type? -- Ian _______________________________________________ svn-src-all@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/svn-src-all To unsubscribe, send any mail to "svn-src-all-unsubscr...@freebsd.org"
