    -- Note: The Inovis documentation mentions an outbound
    -- high port range of 40000-49999.  In passive mode, the
    -- FTP server chooses the port number for the data
    -- connection.  The Inovis server will choose a port number
    -- in the range 40000-49999.  To establish the data connection,
    -- your firewall must allow outgoing connections in that port
    -- range. 

    -- This tells Chilkat FTP2 to establish
    -- an AUTH TLS secure channel after connecting
    -- on the standard FTP port 21.

    -- so disable it:
    EXEC sp_OASetProperty @ftp, 'AutoFeat', 0
