The Serial Device Simulator is useful in the development or testing of products or equipment that expect input (or I/O) from a serial device. For Example,
if data is to be used from a GPS receiver over a serial link, SerDevSim can be used to provide a simulated input mimicking the GPS unit. This eliminates the need for an actual GPS unit for such testing purposes. It also
means that antenna connections, or obtaining a stable reading are no longer factors to interfere with product development. The same is true for product testing, such as test automation on a production line. Stable test
strings provide a signal one can count upon to give consistent test parameters and reliable results. This saves the expense of investing in costly and sensitive equipment.
The Serial Device Simulator also offers the advantage of being more portable than installed equipment.
Since the user can set up the data to be sent, virtually any device with digital data outputs on a serial port, can be simulated.
