This option continuously queries the specified node for a list of its error statistics
and displays the list. As the test runs, the counts in the display can be reset to
zeros by pressing the Space bar.
If you are running the utility on a single-cable network, one of the ‘framing error’
counters will be incrementing continuously due to the open connection on the
monitoring device’s other cable connector. For example, if your single cable is
connected to the Cable A connector, the ‘Cable B framing error’ counter will
increment continuously. In such cases you can disregard the counter.
The option runs continuously and displays a pass count until you terminate it by
pressing Escape.
