This is a PCI expansion card designed to add four serial ports to a computer, allowing for the connection of multiple serial devices such as modems, industrial equipment, or legacy peripherals. It uses the 16850 UART chip for improved data transfer rates and includes IRQ sharing to reduce conflicts with other hardware components. The card features four DB9 female connectors, making it compatible with standard serial cables and devices. It is ideal for users who need to connect multiple serial devices without the need for additional external adapters or hubs.

The card is built for reliability and performance, ensuring stable communication with serial devices even under heavy usage. It supports standard PCI bus architecture, making it compatible with a wide range of desktop computers from the late 1990s through early 2000s. The 16850 UART provides better handling of data flow compared to older UART chips, reducing errors and improving efficiency. This makes it suitable for environments where consistent and reliable data transmission is critical.

Installation requires a free PCI slot on the motherboard and basic knowledge of hardware installation. Once installed, the card should be recognized by the operating system with minimal configuration. It is often used in industrial automation, telecommunications, or for connecting legacy devices that still rely on serial communication. Users may need to install specific drivers or configure IRQ settings depending on their system setup.

The card does not include any additional software or drivers beyond what is typically provided by the operating system. It is a barebones hardware solution that requires no extra accessories for basic functionality. However, it may not be compatible with newer systems that use different expansion standards like PCIe instead of PCI. It also lacks modern features such as USB connectivity or built-in networking capabilities.
