Yes. And the you can read the data in user space process with read().

Why do you want to pass your data through RT-FIFO? You set rt-com to call
your handler (this will be a part of RT-ISR), and your handler reads
that data and performs tasks. If some of your tasks are of lower priority,
use samaphores or signals to wake them up from rt_com handler.
