HP41CL Serial Com Port Failure

[Sylvain Cote]

Neve,
In the file Mark gave you, you will find the log4j2.xml file.
Put that file in the same folder as the clupdate java archive file (.jar).
This specific file is configured to generate a lot of logs. (trace level)
You can change that by modifying the xml file.
Debug level, what it does and available monitoring packages are all described in the xml file.
