probably a silly COM port question

Hi, I need to check whether the COM port on my motherboard is being activated correctly. I have a UPS connected to it, and the installed software refuses to acknowledge that there's anything there. This is a SuSE 10 installation, on AMD64. I've checked in the BIOS that the COM port is "on". Is there a tool in Yast for looking at COM ports?
