'  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.
