Meaning, the program doesn't have access to
that, either.
Terminal scroll locking is not something the
program is ever supposed to have control over. Sending data when not requested could mean data loss, so it really doesn't until told.
But at least it will work in a virtual console, unlike the scroll-lock key. The scroll-lock key only works on physical text consoles(which are probably available via ctrl-alt-f1 through ctrl-alt-f6, if you're curious. ctrl-alt-f7 to get back to X11.)
