The FTP protocol uses a second connection for the data transfer (see RFC959).
When using FTPS, that data connection can be using SSL or not. libcurl will
always tell the server to use SSL, and if the servers responds "OK" libcurl
will use SSL for it. See:

         http://curl.haxx.se/rfc/draft-murray-auth-ftp-ssl-15.txt

Yes, then it will "handshake" the data connection after the TCP connect as it
needs to setup the SSL layer as well.

I can only point out the best FTPS-related link collection I know of:

Yes it does.

If you had read your own logs you already mailed here, you'd know that libcurl
first tries EPSV and then PASV, but that has nothing to do with your problem
here (and no, your server doesn't understand EPSV).
