You can use the Trace option to capture the communication between your client application and the Host Emulator and store it in a trace file. To do this, close the model, navigate to the Model Parameters panel, and select Yes in the Collect Trace box. Click either Submit or Save, and then click Back to the list of models.
You can view a trace on an open session by navigating to the Model Parameters panel, and clicking the Trace button for the particular session. This opens window that displays the trace. As you navigate, this trace window will be updated with the latest trace data.
The trace contains raw hex characters.
