  //  The Inovis EDI VAN requires Passive connections:

  //  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.AuthTls := True;

  //  You'll probably need this property set to True if you're
  //  behind a NAT router or firewall.

  //  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.
