Have you tried using HTerm? It’s one of those hidden gem tools for monitoring serial ports that’s completely free. Perfect for debugging communication issues. Alternatively, you can check out Termite. It’s super lightweight and does the job well.
Another option to consider is the ultimate guide to free serial port monitors. This guide lists several free tools that might fit your needs perfectly.
Yet another suggestion would be RealTerm. It’s free and comes with a bunch of features that are handy for monitoring serial communication. But beware, the interface feels like it’s from the 90s.
Just remember, when you’re dealing with serial communication, ensure your settings on both ends (baud rate, parity, stop bits, etc.) match up. Often, the problem lies in mismatched settings rather than the software itself.
Good luck with your project!
