You can solve this problem using two methods:
Programmatically. If that program works on Windows, you can install our software on the same computer and use the "Spy" mode of our logger, which you may enable in the COM port settings (fig. 5). Our software should start first, before another program start using a COM port.
Using additional hardware. You may make a special data monitoring cable and install our software on an additional computer with Windows, and connect a monitoring tap there.
