  Turns off interactive prompting during

+ .It Fl k Ar seconds
+ Sends a byte after each
+ .Ar seconds
+ period over the control connection during long transfers,
+ so that incorrectly configured network equipment won't
+ agressively drop it.
+ The FTP protocol supports a
+ .Dv NOOP
+ command that can be used for that purpose.
+ This assumes the FTP server can deal with extra commands coming over
+ the control connection during a transfer.
+ Well-behaved servers queue those commands, and process them after the
+ transfer.
