How to Fix PCI Serial Port Driver Issues on Windows

Are you feeling that you are experiencing some issues when trying to connect peripheral components with your PC or laptop? If so, then you can investigate further on this matter to identify if there is an issue with the peripheral components or with the PCI Serial Port driver software. 

In this blog, we will educate you about what is a PCI slot and how to solve its driver-related issues easily. 

What is a PCI slot & PCI Serial Port driver

Coming to what is a computer peripheral first, it is described as a device that is externally connected to a computer and is not a part of the core computer structure. The core components include the Power Supply Unit, the Central Processing Unit, the Motherboard, and the Computer Case containing the core components. Some people also look at peripheral devices as those components which depend on the computer core system to function. 

Peripherals can be categorized into three sections:

  • Storage components: Flash drive, hard drive
  • Output components: Monitors, printers, headphones & speakers
  • Input components: Keyboards, mouse

The PCI stands for Peripheral Components Interconnect. So, a PCI slot is nothing but an old computer bus. It also is a part of the PCI bus standard. The PCI slot is an embedded slot of your Windows machine that allows you to connect hardware devices such as network cards, sound cards, disk controllers, monitors, printers & scanners to your PC or laptop.

A serial port recognizes hardware compliant with the RS-232 standard that can interface with a modem or other communication devices.

What is the PCI driver?

A PCI device driver is software that permits any PCI device to function smoothly when connected to the computer. It forms a programming interface that permits the operating system to interact with the connected device. 

How to identify an issue with the driver of the PCI Serial Port

Now that you have understood what is a PCI slot and driver, so let’s take a look at how to identify issues with it.
