As protocol 2 is considered now as The Only Right Thing, this isn't issue anymore. Please correct me if server side with protocol 2 doesn't do it. I'm unhappy with protocol 2 due to delays mentioned above; it gives very uncomfortable redrawing delays even on 100MB ethernet link. On dialup line these delays become intolerable. /netch To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
