The AIX portmir command can be used to mirror a remote screen on a local terminal. This is a useful diagnostic tool for viewing a remote end user's screen, or possibly mirroring consoles. As a practical matter, both local and remote terminal should be of the same type to avoid screen formatting problems. The portmir command is available in AIX 4.2.1+. See the AIX documentation for more information.
Comment: although the portmir documentation lists "tty's" as the supported terminal type, I've been able to get pseudo-terminals (pts) to work by substituting the appropriate "pts/n" for "ttyn."
