Thanks! As I think about terminals in quite different contexts (credit card terminal, battery terminal, train terminal, etc.) I'm realizing that it's really just any kind of endpoint at all, so pretty much any human interface device (HID) should probably be called a terminal. But when taken to that level, using the acronym TUI (in the "terminal" sense) to mean "not a GUI/CLI" (as if big old consoles or emulators/PTYs thereof are the only type of terminals) seems questionable.
