USB to 25-Pin Serial Port

Serial ports are typically used for legacy communication devices.

Modern computer manufacturers have been doing away with legacy device ports on new computers for years. The problem with this is that if you need to connect a legacy serial device to your computer, you're out of luck. However, Universal Serial Bus (USB) provides a way to connect almost any type of device to your modern computer.

History

Historically, 25-pin and 9-pin serial ports were used to connect a modem to the computer. Currently, serial ports via USB adapters provide connectivity for legacy communications devices.

USB to 25-Pin Adapter

To connect a 25-pin serial device to your computer, you'll need a USB to 25-pin serial adapter. These can be found at online retailers for a modest price. These can be used with USB 1.1 or 2.0 ports and provide an instant high-speed serial port on your PC or Macintosh.

Considerations

Be sure that you actually need to connect a serial device to your computer. Serial ports are often confused with printer parallel ports, which a USB to serial adapter won't support. Keep in mind that you'll need a serial cable for your device as well, as the adapter won't connect directly to the serial device.
