We installed a Windows 7 desktop with an MSI FM2-A55M-E33 Motherboard. I have an add on PCI Card with 1 Parallel DB-25 LPT port and 2 Serial DB-9 COM ports (Syba SY-PCI50009).
The Syba Card works on Com3 but the Com4 port doesn't work. The Motherboard has a Com port header on it as well and I haven't tried connecting to it or disabling it in BIOS. Just wondering if you guys think that is the problem or if there is a more common problem that may be known as causing issue with these cards.
Thank you for your help in advance.
