Modern digital communications may appear to be in a state of disarray. For example, newer data communications protocols like USB and Wi-Fi are not inherently designed to be interoperable with the older serial protocols. However, there are still some things that those older protocols do very well, like connecting the pumps at the corner gas station. In fact, the total number of serial-equipped devices deployed around the planet is not shrinking; it is continuing to grow. This white paper describes the ways in which legacy devices and protocols can be integrated into a wireless world.
