I am wondering if such interrupt is routed to somewhere else? I'd expect it to stay zero unless characters were received or events occurred. Something like (echo "Hello world"; cat ) <> /dev/ttywhatever ought to cause interrupts [That bit of script writes Hello world to the serial port and then copies anything from it back to it until you hit ^C]
