Enables or disables the sending of the FTP protocol PORT command
    to the remote host.

    By default, FTP sends a PORT command when establishing a
    connection. If this command fails, FTP uses the default data
    port (20).

    Disable the sending of the PORT command when you communicate with
    remote hosts that ignore PORT commands.

    Default: ENABLE PORT_COMMAND.
