This is an extremely dangerous patch. A number of terminal protocols have a 'talkback' escape sequence that allow you to write data that the terminal then copies back as if someone typed it. I remember using this feature quite a lot while at Berkeley to, ah, break into people's accounts :-) isprintf() is in there to prevent extranious escape sequences from blowing up the other guy's window. -Matt To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
