Library /sys$common/syshlp/tcpip$ftp_help.hlb ENABLE, VMS_PLUS  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    Enables or disables VMS Plus Mode. This lets you specify a
    transfer mode based on file type, for example, ASCII or image.

    With VMS Plus Mode disabled, FTP does not send the FTP SITE
    command. (Older implementations of the FTP server do not support
    this 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 either:

    o  +VMS+ - The client is in VMS Plus mode.

    o  NONE - The client is not in VMS Plus mode.

    Defaults:

    o  When you use FTP to connect to an OpenVMS host running TCP/IP
       Services for OpenVMS, VMS Plus Mode is enabled.

    o  When you use FTP to connect to a non-OpenVMS host or a VMS
       system running software that does not recognize VMS Plus Mode,
       VMS Plus Mode is disabled.
