From the terminal to Emacs.
Cursor up typically is
ESC [ A
three characters. Curses applications behave differently if you type those
three characters, one-by-one, because of timing.

Typically the _application_ (Emacs) waits for completion of a control sequence.

That's part of it. Usually the input (from the terminal to the application)
is more important.
