Dell Optiplex 780 PCI Serial Port: What It Is and Why You Need It

If you own a Dell Optiplex 780 desktop computer, you may have noticed that there are two devices in the Device Manager that are missing drivers: the PCI serial port and the PCI simple communication controller. What are these devices and why do you need them?

The PCI serial port is a hardware interface that allows your computer to communicate with other devices using a serial protocol. Serial communication is a method of transferring data one bit at a time, using a single wire or a pair of wires. Serial communication is often used for connecting modems, printers, scanners, barcode readers, and other peripherals to your computer.

The PCI simple communication controller is a component of the Intel Active Management Technology (AMT) system, which is a feature of some Intel chipsets that allows remote management and monitoring of your computer. AMT enables you to access your computer’s hardware and software information, perform diagnostics, update drivers and firmware, power on and off your computer, and more, even when your computer is turned off or not connected to a network.

Both the PCI serial port and the PCI simple communication controller are important for the optimal performance and functionality of your Dell Optiplex 780. Without the proper drivers, these devices may not work correctly or cause errors and conflicts with other devices. Therefore, it is recommended that you install the latest drivers for these devices from the Dell website or from other reliable sources.

How to Install the Dell Optiplex 780 PCI Serial Port Driver

If you want to install the driver for the PCI serial port on your Dell Optiplex 780, you can follow these steps:

1. Go to the Dell support website at https://www.dell.com/support/home/en-us/product-support/product/optiplex-780/drivers and enter your service tag or browse by product.
