Once the driver is installed, you should be able to see that it's functioning correctly in Device Manager. You can also test the serial port by opening a terminal emulator program such as HyperTerminal or PuTTY and attempting to connect to a serial device.

In addition to the PCI serial port driver, Dell also provides a range of other drivers for its Optiplex series, including audio, video, and BIOS chipset drivers. These drivers are available for download from Dell's website and can be installed using a similar process.
