+Long: ftp-pasv
+Help: Use PASV/EPSV instead of PORT
+Protocols: FTP
+Added: 7.11.0
+See-also: disable-epsv
+---
+Use passive mode for the data connection. Passive is the internal default
+behavior, but using this option can be used to override a previous --ftp-port
+option.
+
+If this option is used several times, only the first one is used. Undoing an
+enforced passive really isn't doable but you must then instead enforce the
+correct --ftp-port again.
+
+Passive mode means that curl will try the EPSV command first and then PASV,
+unless --disable-epsv is used.
