    // The Inovis EDI VAN requires Passive connections:
    ftp.put_Passive(true);

    // 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.
    ftp.put_AuthTls(true);

    // You'll probably need this property set to true if you're
    // behind a NAT router or firewall.
    ftp.put_PassiveUseHostAddr(true);

    // The Ssl property is for establishing an implicit SSL connection
    // on port 990.  Do not set it to true.  The Inovis VAN
    // uses explicit encryption (SSL/TLS).
    ftp.put_Ssl(false);

    // The Chilkat FTP component automatically sends a "FEAT";
    // command after connecting.  This allows the component
    // to better know the FTP server's capabilities.
    // The Invois server doesn't recognize the FEAT command,
    // so disable it:
    ftp.put_AutoFeat(false);

    // Connect, convert to TLS, and login to the FTP server.

        // successful. This allows you to visually verify
        // that the secure connection actually occurred.
