At first, sorry, this was my mistakte not having looked, whether rtai_serial
is loaded.
the problem I have, concerns only the rtai-serial, not my application module
(to this point of time :-)).
I could patch "serial.c" after removing my former modifications. To specify
my problem more:
The module  rtai_serial.ko.cannot be loaded, therfore I could not load my
application-module.

As consequence of my module-loading routines, my computer hangs up.

I proceed as follows:
    setserial -g /dev/ttyS*

shows my serial ports, everything is ok,

I insert the module for rtai,scheduler,fifo,shm,semaphore, everything is
well,
When I insert the module rtai_serial.ko I got the message:

-1 Permission denied

This is the dmesg-report:

And after typing
    setserial -g /dev/ttyS*

my computer hangs up.  I cannot explain the errormsg
Permission denied

In the dmsg-report is the following line:
 14 is a wrong index module for lxrt

What does it mean?
