PCi Serial Port Driver For Windows 7/10/11 64-Bit Download

Here is the simple and easiest way to download the latest setup of PCi serial port driver. The PCI Serial Port driver is a software component that facilitates communication between a computer’s operating system and a serial port device that is connected to the computer through a PCI (Peripheral Component Interconnect) slot. Serial ports are used to connect various types of devices, such as modems, serial printers, barcode scanners, and other industrial equipment, that rely on serial communication protocols.


PCI Serial Port Driver is an important software for your computer and it should be updated regularly to avoid any problems. You can do this using the Windows Device Manager or by downloading a professional driver update tool like Advanced Driver Updater. You should also make sure that your system is clean and free from malware or third-party programs that may interfere with the installation of this driver.

When a PCI serial port driver is installed it creates a COM port in the operating system that shows up as if it was a built-in COM port. Ideally the COM port can be configured to have various settings that are controlled by the driver. However, some cards have badly written drivers that cannot be configured.

Normally the computer is plug-and-play so the serial port is automatically detected and located by the operating system. It is then loaded with a driver and ready for use.

However, sometimes the process does not go as planned and a number of different errors can occur. Some of these errors can cause a yellow mark to appear besides the PCI Serial Port driver in the Device Manager. If this error is not resolved, you might not be able to update the driver for this device and your system will not function correctly.

How it works

If you run a scan with a utility like a driver scanner, this can help identify the cause of this problem and fix it automatically. However, if the issue is still not resolved, you might need to try installing the driver manually. There are a few ways you can do this, but they are not always guaranteed to work.

One way is to perform a Clean Boot, which means that only essential programs are allowed to run on the PC at startup. This can help you find out if the problem is caused by a third-party program that conflicts with Windows or corrupted system files.

Another way is to download a driver from the manufacturer’s website and install it manually on the PC. This method requires some technical knowledge and can be time-consuming. You should also be careful to ensure that you download the correct driver for your specific hardware.



You can also try searching for a compatible driver on the Windows driver store. This is a useful tool to have and it can save you a lot of time and effort. However, there is a chance that the Windows Driver Store may not be able to locate the correct driver for your PCI Serial Port Driver.

You can also check the /proc/interrupts file or the /proc/ioports file to see if there are any entries for your serial ports. If you have trouble finding the right IRQ and IO address you can try using the setserial command to set them. However, you should note that this is not a reliable method since the kernel will revert the changes if it detects that another interrupt is being used at the same IRQ.

When a PCI Serial Port driver is installed and functioning correctly, it allows the operating system to recognize the serial port device, manage data transmission and reception, and provide a way for applications to interact with the connected device. This driver ensures that data can be sent and received in a reliable and standardized manner, adhering to the appropriate serial communication protocols (such as RS-232, RS-485, etc.).

Supporting Platforms

In modern computers, especially laptops and desktops, serial ports are becoming less common due to the prevalence of USB and other more advanced interfaces. However, in certain industries and applications, serial port devices are still used extensively, and having the appropriate driver is crucial for their proper functioning.

To install the PCI Serial Port driver, you usually need to follow these steps:

  1. Identify the Hardware: Determine the manufacturer and model of the PCI Serial Port device that requires the driver.
  2. Download the Driver: Visit the manufacturer’s website or the computer’s motherboard manufacturer’s website to find the appropriate driver for the specific PCI Serial Port device and the operating system you are using.
  3. Install the Driver: Run the downloaded driver installation package and follow the on-screen instructions to install the driver. This might involve extracting files, running setup programs, and restarting your computer.
  4. Verify Installation: After installation, the operating system should recognize the PCI Serial Port device without any exclamation marks or warnings in the Device Manager.
  5. Configure Applications: If you have specific software applications that need to communicate with the serial port device, configure those applications to use the correct serial port settings, such as baud rate, parity, stop bits, and data bits.

Remember that the steps might vary slightly based on the specific operating system and hardware you are using. If you’re having trouble finding the appropriate driver or encountering issues during installation, referring to the manufacturer’s support resources or online forums can often provide helpful guidance.
