USB Serial Adapters

Serial ports are less frequently used than the far more common USB port. However, they do tend to connect computers to some of their most vital components, including modems and serial printers. It's a very serious situation, therefore, when a computer user finds himself running out of serial ports. That computer user should probably look towards investing in a USB serial adapter.

The advantages of such a simple purchase are extensive. For one thing, with a USB serial adapter, you can transform one of your ordinary USB ports into one, two, or even more serial ports, giving you plenty of extra connectivity options. The resulting versatility that this lends a personal computer is extraordinary--and extraordinarily useful to many professionals and amateurs.

One of the many USB serial adapters that we stock here at Byte Runner Technologies is the popular PL-4COM. It can be installed very easily: simply plug it into your USB port and the computer will automatically detect the port change. The result is four extra serial communication ports that you can then use for many different accessories.

The four port PL-4COM is only one of the many expansion options that we offer here at Byte Runner Technologies. We stock a range of different external USB/Firewire drive enclosures, ATA controller cards, and distinctive ring routers, among many other products. Each of these comes with free technical support via our toll-free technical service hotline.
