Turns off VMS Plus Mode. This lets you specify a transfer mode
    based on file type (for example, ASCII or image).

    Disables the sending of the FTP SITE command for older
    implementations of the FTP server, which do not support the SITE
    command. The FTP client uses the FTP SITE command to identify
    itself (its SITE type) to the remote host. The SITE type of an
    FTP client can be one of the following:

    o  +VMS+-the client is in VMS Plus mode

    o  NONE-the client is not in VMS Plus mode

    Defaults:

    o  When you FTP to an OpenVMS host, VMS Plus Mode is enabled.

    o  When you FTP to a non-OpenVMS host, VMS Plus Mode is disabled.
