I use qextserialport for serial programming,but I can't open the port from /dev/ttyS0 to /dev/ttyS8.Then I change my right using: usermod -G uucp ..,the result is as the same.
Can anybody tell me why?How can I deal with it?Thank you very much!

what does 'll /dev/ttyS0' return?
When you run the application as root, does it work then?
