    Teletype Terminal

    The teletype terminal model is a serial teletype (TTY) terminal model.

    The main features of the model are as follows:

    • Fully bi-directional - received serial data is displayed as ASCII characters whilst key presses are transmitted as serial ASCII data.
    • Simple two wire serial data interface: RXD for received data and TXD for transmitted data.
    • Simple two wire hardware handshake interface: RTS for ready-to-send and CTS for clear-to-send.
    • Baud rate from 300 TO 57,600 baud.
    • 7 or 8 data bits.
    • Odd, even or no parity.
    • 0, 1 or 2 stop bits.
    • XON/XOFF software handshaking in addition to hardware handshaking.
