Enables 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.

    o  Use ENABLE CRMOD if your terminal expects each line to end
       with Return LF.

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