SERIAL PCI DUAL 16550 9 PIN SIIG

If you've run out of serial ports on your computer, before you buy an ISA card to add more serial ports, check one thing first: how many IRQ's (Interrupt Request lines) do you still have free? If you're down to only one, better get a PCI card like SIIG's Dual Plus PCI. The reason is that a PCI 2.1 compliant card can allow multiple devices to share a single IRQ setting. What's more, a PCI card reduces the load on your CPU, improving overall system performance. The CyberSerial Dual Plus PCI I/O card adds two high-speed 16550 UART 9-pin serial ports to your computer, with baud rates up to 460Kbps.
