A very simple kernel debugger has been added to the JNode nano-kernel. This debugger is able to send all data outputted to the console (using Unsafe.debug) to another computer via a null-modem cable connected to COM1.
From the other computer you can give simple commands to the debugger, such as dump the processor thread queues and print the current thread.
The kernel debugger can be enabled by adding " kdb" to the grub kernel command line, or by activating it in JNode using a newly added command: "kdb".
