Testing RS232 & RS485 Windows CE Dev, board 3.1

Hi,
Thank you for your answer.
I fixed the RS232 Problem and it works fine, now i still have a problem with the RS485 testing
after following the link you mentioned i couldn’t find the UARTX in my registry settings,
So i still can’t figure out how to test the RS485 communication on my colibri board, could you help me with some links (tutorials, or hardware needed to the the testing) because the toradex developper doesn’t have any support or instruction for it (hardware or software).

Thank you

Best Regards
