    S1200SPL can't connect to COM (RS-232) device (APC Smart-UPS SC620VA).


      Serial port is enabled in BIOS.

      The same device with the same cable successfully connected to another motherboad (asus z97-a), so device problem is excluded. Tried Win2012,Win2008R2,Win8.1

      Should I change something else on this motherboard to make it work with UPS by serial port?
