PCI chip solution( SB16C1052PCI)

It's real COM Port in your computer, high compatible with serial type device.

The 4-Port PCI Serial Adapter Card (RS232) with 161050 UART adds four DB9 RS232 serial ports, using a single PCI expansion slot.

The card delivers an efficient single-chip design and a large 256-byte transit/receive FIFO buffer that work together to provide high-speed serial communication while reducing the overall load on the system CPU. 

With the included standard and low profile/half-height brackets, this PCI serial expansion card suits a broad range of system form factors, and is a perfect addition for connecting RS232 serial devices to a host computer. For added versatility, the RS232 adapter is able to accommodate 3.3 or 5V PCI/PCI-X slots
