Enables the transmission of data in binary mode.
    o  Enabled - The EOL (end-of-line) character is not mapped to
       Return LF (the carriage return/line feed combination).
       Use ENABLE BINARY when the remote host expects each line to
       end with a carriage return/line feed combination.
       Binary mode provides interaction when the remote host:
       -  Expects special characters.
       -  Does not support automatic negotiation of the TELNET binary
          option.
    o  Disabled - EOL is sent as Return LF (the carriage return/line
       feed combination).
