Why use a serial monitor?
If you are having an issue with your iSpindel the serial monitor is a quick diagnostic tool you can use to see what’s going on behind the scenes. It can display error messages that give clues on what to investigate.
Different Chips
The CH340x chip is featured in the video, but the CP210x chip is becoming more popular. From the Device Manager, you can look at properties on the General and Port Settings tabs for additional information.
Collecting serial monitor logs, please help out.
If you are having an issue with your iSpindel and the issue has manifested itself in the serial log I would appreciate it if you could share the serial monitor log with me and what the fix was. I will post it here and hopefully it can help others. Please email it to me at JoeyJoeJoeJr.OSD@gmail.com.

I will continue to add serial logs for issues with fixes. If you having issues that aren’t found on this website you can search through the history of issues on the official iSpindel GitHub page.
