Well, a stock debian one out of sarge, kernel-image-2.6.8-1-686-smp, configs 
at http://www.stewarts.org.uk/stuff/config-2.6.8-1-686. There is not much 
difference between a stock 2.6.8.1 and the debian 2.6.8:-

porttest.c:
#include <sys/fcntl.h>
#include <sys/ioctl.h>
main(int argc, char ** argv) {
        int r, fd = open(argv[1], O_RDWR|O_NOCTTY);
        r=ioctl(fd, TCSBRKP, 20);
        printf("%d\n", r);
        close(fd);
}

$ ./porttest /dev/ttyS0
0
$ ./porttest /dev/ttyUSB0
