I do not doubt it. They are codes meant specifically for those terminal
emulators so it's no wonder they do what you want there. Try it on
a wyse terminal, or in the Linux console. M-x shell is not a terminal
emulator. M-x term is more likely to do what you want (tho I do not
guarantee that all those escape sequences are supported, especially the
one that sets the window title).
