The mechanical teleprinter was replaced by a "glass tty", a keyboard and display screen emulating the teleprinter. "Good" terminals permitted extra features, for instance cursor motion more click here than the complete display screen, or local editing of data about the terminal for transmission to the pc. Given that the microcomputer revolution changed the traditional �?minicomputer + terminals �?time sharing architecture, hardware terminals had been replaced by terminal emulators �?Personal computer program that interpreted terminal alerts despatched through the PC's serial ports.
