Re: PutFile and Resume (General questions)
Roman,
Seems that Core FTP doesn't reply on PORT command with 200 response, but decides to use 250. By RFC specification from 1985
http://www.faqs.org/rfcs/rfc959.html
you will see that correct response to PORT is 200 - thus component is confused and awaits wrong response. Since 250 is also used during data file transfer, component expects 250 to close the data which doesn't happen - and it times out.
You should mark this complaint to Core FTP authors to be fixed.
