I was searching how to debug the fiasco kernel through JDB. The following link gives a good approach how to it through minicom.

However, even if I see the messages on the screen, is it possible to interact with JDB without having an exception? I looked at also the "Fiasco Kernel Debugger Manual", however, I couldn't figure out how to exactly interact with JDB. Until now I could only interact with JDB in case of any exception occurrence. 

Thanks in advance.

Sincerely,
