Serial PCI Card, 2 ports RS232

If you need to create serial ports in a desktop computer and you have a motherboard which has an available PCI slot then using a serial PCI card is the best way to do this. Using a PCI card instead of for example a USB to serial adapter is better due to slightly lower latencies and less driver incompatibilities; the reason is because the card is connected in a more direct way to the motherboard. The disadvantage is that you need to open up your computer to install the serial PCI card and sometimes the driver software for the card does not offer as many adjustable COM port settings as for example a USB to serial adapter does.

This serial PCI Serial card high performance processor (MSC9865) from MosChip Technology/ASIX which provides superior performance and reliability compared to many other cards in this price range.
