This sample depends on the following libraries :
First off all, this application may be used to cause exceptions (product reset due to a software crash, and backtrace storage in the product memory). This may be done with the +BUG command.
Then, it is possible to know how many backtraces are stored in the product, and to retrieve them through the 1K XModem uploader with the +GETBKTRC command. The upload operation is processed by the Download library.
Finaly, it is also possible to erase all backtraces stored on the product, using the +ERRBKTRC command.
