For things that need to work with low-level data like that you'd be much better off using syswrite instead of print.

Not only will syswrite not bother scanning the string for variable substitutions and such, but syswrite returns the number of bytes actualy written.

So instead of print DEST "$n" x $input; you should put in $written=syswrite(DEST,($n x $input)); and terminate when $written!=(length($n)*input)
