This section explains how to use SI_SCOPE's Memory Window. The memory window lets you scroll through an internal buffer that contains a recording of the comport activity up to that point. The internal buffer is a finite circular buffer, so it is possible that you will not be able to view the entire session if the session is very large. The size of the buffer is controlled through the "Capture Buffer Size" setting from the "Set Run Time Options" dialog box in ScopeCfg.
