Disables the mapping of received carriage returns. With this
    mapping, the remote host sends each line with Return LF (the
    carriage return/line feed combination) at the end of each line.

    Use DISABLE CRMOD if your terminal expects Return null at the end
    of each line.

    Default: DISABLE CRMOD.
