The PCI8S950LP PCI Serial Card (16950 UART) lets you turn a single low profile PCI slot into eight RS232 (DB9) serial connections. The unique design of the serial card and included break out cable feature a VHDCI (Very High Density Cable Interconnect) connector, enabling the addition of 8 serial interfaces while only using a single expansion slot. The 8-port serial adapter card is compatible with a broad range of operating systems, including Windows 2000/XP/2003/Vista/7, as well as Linux Kernel 2.4.x and up.
