easy:SetOpt_FTP_Response_Timeout(timeout)
timeout period (in seconds) on the
amount of time that the server is allowed to take in order to send a response
message for a command before the session is considered dead. While libcurl is
waiting for a response, this value overrides #CURLOPT_TIMEOUT. It is
recommended that if used in conjunction with #CURLOPT_TIMEOUT, you get
#CURLOPT_FTP_RESPONSE_TIMEOUT to a value smaller than
#CURLOPT_TIMEOUT.
