One way is using select, as premchai21 mentioned. An example of this is: 
$previous_fh = select(STDOUT); #selects STDOUT and saves the selected 
+filehandle/handle

$| = 1; #auto-flushes STDOUT

select($previous_fh); # restores the previous filehandle/handle

Or you could use SelectSaver - which is used to save and restore a selected filehandle. Or follow chromatic's suggestion. :)
