StarTech.com Serial Port Cards PCI2S4851050 Editorial Review
The StarTech.com 2 Port PCI RS422/485 Serial Adapter Card with 161050 UART offers rapid shipping and good quality. However, some customers had trouble making it work in a Windows XP environment and ended up using a StarTech RS422 to USB converter instead.
