hello again  :) 
where are I can insert code for poweroff ups on OB LB before shutdown computers?
i try insert it to upsdrv_shutdown, but it's not work. Why?

static void shutdown_ret(void)
{
    ser_send_char (upsfd, SHUTDOWN0);
    ser_send_char (upsfd, SHUTDOWN);
    if (types[type].shutdown_arguments.minutesShouldBeUsed != 'n')         ser_send_char (upsfd, '\x00');
    ser_send_char (upsfd, '\x10');
    upslogx(LOG_INFO, "Shutdown (return) initiated.");
    exit (0);
}

void upsdrv_shutdown(void)
{
    /* power down the attached load immediately */
    printf("Forced UPS shutdown (and wait for power)...\n");
    shutdown_ret();
}

powercom driver not send this bytes (SHUTDOWN0,SHUTDOWN) :(
