UNIX System V certainly was connected to serial terminals (Televideo, VT100, ...) and it had the VI visual editor with definitively cursor movement across the screen, even when the terminal had no cursor keys. cursor movement is not tied to memory-mapped devices, and even old DOS Software (MS Word and friends) were derivative of CP/M software where they also have to live with serial terminals. they (for the most part) used only BIOS funtions for screen control. only much later direct memory control became en vogue.
