Whoosh! You're still missing the point that what matters is the other end of the connection, and whether the user-facing side can handle character events determines whether vi can respond to characters in (near) real time. SSH carries traffic for other protocols, e.g., SFTP.

I already made the point that Vim is running over SSH so take 3270 and Telnet out of the discussion. 3270 was designed for networks in the dark ages. ISPF is still a brilliant platform but it’s no match for ncurses applications that can now leverage cool unicode fonts and other stuff. > > > -- > Shmuel (Seymour J.)
