//  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.
