    it's very simple, just gcc and run it from console, I guess you should
    quit X before running it, ctrl-c to exit:

    #include <stdio.h>
    #include <unistd.h>
    #include <sys/types.h>
    #include <sys/stat.h>
    #include <fcntl.h>

    int main(void)
    {
    unsigned char buf[10];
    unsigned char last;
    unsigned long counter = 0;

    int fd = open("/dev/psaux", O_RDONLY);
    if(fd == -1) { perror("couldn't open file"); exit(1); }

    while(read(fd, buf, 1) != -1) {
    if( (last == 0) && (buf[0] != 0) ) {
    printf("\n[%010d] ", counter);
    }
    printf("[%03d] ", buf[0]);
    last = buf[0];
    counter++;
    }

    return 0;
    }
    /* eof */
