Product Information
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 CyberSerial Dual 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.Product Identifiers
