The automatic negotiation mode acts on configured port number 21 and server
features, it tries to negotiate with explicit TLS via AUTH TLS. If the specified port
is any other, it tries to negotiate in a similar way.
Using FTP without TLS encryption gives the FTP client reduced capabilities. This
mode is only for accessing disturbance recorder data from the IED.
If normal FTP is required to read out disturbance recordings, create
a specific account for this purpose with rights only to do File
transfer. The password of this user will be exposed in clear text on
the wire.
