I am having some problems getting the timer device to work...  Specifically, I
can do a GETSYSTIME with no problem, but an ADDREQUEST always locks up the
computer...  I have tried several examples from several books and none of them
work either (are they all THAT bad???).  Here is my latest attempt, where the
GETSYSTIME works, but it locks up on the second DoIO when I try to perform an
ADDREQUEST.  Any help would be VERY VERY appreciated!!

#include "exec/types.h"
#include "exec/lists.h"
#include "exec/nodes.h"
#include "exec/ports.h"
#include "exec/io.h"
#include "exec/devices.h"
#include "devices/timer.h"

#define msgblock tr.tr_node.io_Message

struct timerequest tr;

main()
{
    int error;

    error = OpenDevice(TIMERNAME,UNIT_VBLANK,&tr,0);
    msgblock.mn_Node.ln_Type = NT_MESSAGE;
    msgblock.mn_Node.ln_Pri = 0;
    msgblock.mn_Node.ln_Name = NULL;
    msgblock.mn_ReplyPort = NULL;

    tr.tr_node.io_Command = TR_GETSYSTIME;
    DoIO(&tr);
    printf("\nSystem Time is:\n");
    printf("Seconds Microseconds\n");
    printf("%10ld %10ld\n",tr.tr_time.tv_secs,tr.tr_time.tv_micro);

    tr.tr_node.io_Command = TR_ADDREQUEST;
    tr.tr_time.tv_secs=10;
    tr.tr_time.tv_micro=0;
    DoIO(&tr);

    tr.tr_node.io_Command = TR_GETSYSTIME;
    DoIO(&tr);
    printf("\nSystem Time is:\n");
    printf("Seconds Microseconds\n");
    printf("%10ld %10ld\n",tr.tr_time.tv_secs,tr.tr_time.tv_micro);
    CloseDevice(&tr);
}
