     Option      Description

     CCC         Clear Control Channel connection option is useful
                 when the copy must pass through a firewall. The
                 Control Channel data is not encrypted so the
                 firewall knows which port to open for the Data
                 Channel.

     DATA        All transmission data is encrypted.
     (default)

    The underlying TCP/IP Networking product must recognize this
    qualifier and must support SSL encryption in order for this
    qualifier to have an effect.
