' 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.
