[W/K] :: remote echo

  remote echo
       
           (Obsolete: "full-duplex") A mode of operation
          of communicating programs or devices in which the sending
          system does not display the characters the user enters, but
          only sends them to the remote system which then "echoes" them
          back to be displayed to the user.  This lets the operator see
          not only typing errors, but also transmission errors.  This is
          now the usual mode of most systems with remote users.
       
          Contrast: local echo.
