// The Inovis EDI VAN requires Passive connections:
ftp.Passive := 1;

// 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 := 1;

// You'll probably need this property set to 1 if you're
// behind a NAT router or firewall.
ftp.PassiveUseHostAddr := 1;

// The Ssl property is for establishing an implicit SSL connection
// on port 990.  Do not set it to 1.  The Inovis VAN
// uses explicit encryption (SSL/TLS).
ftp.Ssl := 0;

// 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.AutoFeat := 0;

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