#  The Inovis EDI VAN requires Passive connections:
ftp.put_Passive(True)

#  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.put_AuthTls(True)

#  You'll probably need this property set to True if you're
#  behind a NAT router or firewall.
ftp.put_PassiveUseHostAddr(True)

#  The Ssl property is for establishing an implicit SSL connection
#  on port 990.  Do not set it to True.  The Inovis VAN
#  uses explicit encryption (SSL/TLS).
ftp.put_Ssl(False)

#  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.put_AutoFeat(False)

#  Connect, convert to TLS, and login to the FTP server.
success = ftp.Connect()
if (success != True):
    print ftp.lastErrorText()

    #  LastErrorText contains information even when
    #  successful. This allows you to visually verify
    #  that the secure connection actually occurred.
