Does Plan 9 have any Unix-like terminal emulators?
The Plan 9 window system doesn’t obey any inline cursor controls, since none of the native applications use cursor-addressing. If you want to get from Plan9 to Unix systems, you can run /bin/hp in one of your windows, telnet/rlogin to Unix, and set the term/TERM variable to hp2621 on the Unix end. See hp(1) for more details.
