A tool for monitoring serial communication

[SVint]

Hi everyone
I’m trying to debug a USB-to-serial (COM port) connection on Windows and need a way to see what’s being sent and received.
I’m not sure what tool I should be using. I’m looking for something that can show data in real time (both directions) handle both text and binary data and help catch missing or corrupted messages.
Any recommendations or things I should look for?

You need more than just a tool that can monitor and analyze serial traffic. Simple tools can show data, but they’re not great for real debugging, especially with binary data or intermittent issues. I came across an article that compares different tools and approaches, which might help you decide what fits your case best https://www.com-port-monitoring.com/best-free-serial-port-monitors/
