4.7.7.5 List of all Event Symbols
By default, the Event Display shows all events, which includes control signal changes, start and end of frame
characters and flow control changes. If you want to see only the data bytes, click on the All Events button .
Click again to display all events.
Click on a symbol, and the analyzer displays the symbol name and sometimes additional information in the
status lines at the bottom of the
Event Display window. For example, clicking on a control signal change
symbol displays which signal(s) changed.
In addition to data bytes, the events shown are (in alphabetical order):
Symbol Event
Abort
Broken Frame - The frame did not end when the analyzer expected it to. This occurs most
often with protocols where the framing is indicated by a specific character, control signal
change, or other data related event.
Buffer Overflow - Indicates a buffer overflow error. A buffer overflow always causes a
broken frame.
