A PCI Express card with parallel and two COM ports typically allows you to add additional parallel and serial communication ports to your computer system by connecting to a PCIe slot on your motherboard. Here are the typical details you might find for such a card:

1. Interface: PCI Express (PCIe) interface, which provides high-speed data transfer between the expansion card and the motherboard.

2. Parallel Port: One parallel port (also known as a printer port or LPT port) for connecting parallel devices such as printers, scanners, and external storage devices. The parallel port uses a 25-pin D-sub connector.

3. COM Ports: Two COM ports (also known as serial ports) for connecting serial devices such as modems, barcode scanners, and serial printers. Each COM port typically uses a 9-pin D-sub connector.

4. Compatibility: Compatible with standard PCI Express slots on desktop computers. Ensure that your motherboard has an available PCIe slot and is compatible with the expansion card.
