Hello Slobodan,

Well I'm trying to use WinDBG.exe ~ this is where I am getting the
output across the COM port for the messages, in the command window.

In the pane where I should be able to enter the commands you
suggested, I cannot enter commands and it has the text "Debuggee not
connected".

Any advice on how to establish a real connection where I can enter
your suggested commands?

Thanks,
SAC
