Can you elaborate on the problem ?
what does the application do with .txt files if they are not sucked
up by tty ?

Awnsering whenever a program halts or runs forever is
On a turing machine, in general impossible (turings halting problem).
On any real computer, always possible as a real computer has a finite number
of states N, and will either halt in less than N cycles or never halt.
