From the developer:
GPINTCheck will allow you to verify that your computer, the GPINT-PT, cable, and your mount are all working together. This procedure should be performed before you go out to try to autoguide and can be done indoors without a guide imager attached to the computer.
GPINTCheck allows your system to be verified independent of any third-party autoguide
software, and thus is a useful troubleshooting tool as well.
