Historically, COM ports served as the primary gateway for serial communication—connecting everything from modems to mice—while LPT ports were the standard for parallel printer connections. While modern motherboards rarely include these physical headers, the logical "COM & LPT" category still exists within the Windows Device Manager to support virtual serial ports, USB-to-serial adapters, and PCI-expansion cards.

Visit the official WCH website. Their CH352 or CH353 PCIe dual-serial/parallel drivers frequently correspond to 17-11 configurations.
Generally, the installation process is straightforward:
Modern versions of Windows require all drivers to be digitally signed by Microsoft. If your legacy driver lacks this signature, Windows will block the installation.
Modern motherboards no longer feature native serial or parallel port chips directly on the board. Instead, you must install a PCI Express (PCIe) expansion add-in card to gain these ports. The "17-11" identifier alerts the OS that a third-party multi-I/O controller handles data bridging, requiring highly specific architecture drivers rather than standard Microsoft generic port drivers.
