(3) Anonymous FTP automatic logon. Currently, most FTP sites can log on anonymously, while ncftp can log on automatically (default ).
(4) supports transmission through the firewall and proxy server.
(5) supports the bookmarks function. You can place a position in the bookmarks to facilitate future jump.
(6) The download progress is displayed.
(7) display the transmission rate.
(8) The file list is automatically suspended when the page is full. When the LS file list exceeds one screen, ncftp will automatically pause and wait for any key to continue.
