How to Build a USB to Serial Converter
The universal serial bus (USB) is now the industry standard for connecting peripherals to a computer. The USB has gone through a few alterations since it was first introduced as the replacement to the original serial connection port. More and more computer manufacturers are now avoiding the serial port as it is big and bulky compared to the USB. You can, however, still use your serial devices on your computer, but an adapter is needed along with a few other cables. Once you have the hardware, building the converter is very simple.
