Rt Tests and gnulinux Tests

Real Time Orocos Core, now works, but we have more questions about the orocos tests
When we run a test in gnulinux system we can see a  lot of text like :

( e.g. test_FifoRT-gnulinux)

[[[ test_FifoRT loading... ]]]

received 18 bytes: Test message 

[[[ test_FifoRT unloaded.. ]]]

and so on...
but when we run a test in rtai system we see only messages like :

You are root
Module test_FifoRT-rt loaded with warnings (no GPL license)
PASS: test_FifoRT-rt.sh
..

Is this normal? why cannot we see a significant output?

Can you explain to us the role of module.c  ?

int init_module( void )   <-- ok
{
    DO_GLOBAL_CTORS();  <--What does this function do?

    initFramework();        <--startup  the Framework, but what does exactly do ?
    rtos_printf( "\nCore loaded\n\n" ); <-- this text doesn't appear on the
monitor. Why? 
    return 0;              <-- ok
}
