Still stuck on the basics

[Neal Tanner]

1)  When I run the examples under /usr/realtime/testsuite/user they
    generate output telling me to use Ctrl-C to exit (preempt even
    starts scrolling data) but when I press Ctrl-C, the entire machine
    locks up.  Do I have something configured wrong in rtai?  Any
    ideas?

2)  I am still a little confused on what modules I do or do not need
    and how they correspond to the 24.1.x modules that I have been
    using.  Here are the modules that I used to use and my best
    guesses.  Are there other modules that I will need as well?  Any
    clarifications would be appreciated.

    rtai --> adeos & rtai_hal ???
    rtai_sched --> rtai_up
    rtai_shm --> rtai_shm
    rtai_utils --> ???
    rtai_fifos --> rtai_fifos
    rtai_libm --> rtai_math


3)  I am trying to go back and get my existing code running with
    rtai-3.0. I made sure that the option for backwards compatibility
    was enabled in the configuration menu, but "nam2num" is generating
    implicit declaration warnings and unresolved symbol errors.  I
    think that I pulled my usage (shown below) of rtai_kmalloc
    straight out of the 24.1.x programming guide.  Is "nam2num" part
    of rtai or have I screwed up something seperate?

    state = rtai_kmalloc(nam2num(MODULE_SHMNAME), sizeof(struct 
module_state));

4) I got started on this whole project because we are upgrading the
    machines in our lab to Redhat 9 and I since I was going to have to
    reinstall rtai, I figured the newest version would be a good idea.
    Is it?  Currently, we use a very small subset of the capabilities
    of rtai (mainly executing a couple of servo loops at a few
    kilohertz and moving some data through shared memory for display
    purposes).  Are we better off going back to 24.1.x since we know
    how to use it (at least somewhat)?  Does anyone have a feel for if
    I'm anywhere close to having this working yet?

Sorry for the long barrage of questions this time around, but thanks
so much for any help you can be.
