(Node.js) Inovis VAN FTP/SSL (EDI)

Demonstrates how to connect to the Inovis EDI VAN (FTP/SSL).

    // 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.

    // on port 990.  Do not set it to true.  The Inovis VAN
    // uses explicit encryption (SSL/TLS).

    // The Chilkat FTP component automatically sends a "FEAT";
    // command after connecting.  This allows the component
    // to better know the FTP server's capabilities.

    // so disable it:
