Yes, of course, because DOS itself doesn't uses machine resources until

Kind of depends on your task priority needs and data collection, interface,
latency, and throughput requirements. You could use FreeDOS for a
stock-ticker program without fear, but I would stay
if the real-time is INSIDE your program: yes
if you want a real-time-OS to run many programs: no

As it is currently a quite active development project, any nontrivial
