=================================================================
To run this I did
insmod rlt_sched
insmod rtl_nfifo
insmod rt_com
insmod tr_process <- my test example.
Everyting seems to go fine but nothing happens: Nothing is written in the line.
Could you please give some advice?
Thanks a lot for your time.
