Use Scroll Lock key for terminal flow control

So, my Scroll Lock key doesn't have much use, while I keep hitting Ctrl+S with no intention of stopping control flow. I know how to disable Ctrl+S from locking scroll (stty -ixon), but can I use Scroll Lock key instead for the same use? **- UPDATE -** In my terminal Scroll Lock does not stop control flow. My question is how to assign that function to that key.
