front panel and monitor the results using both the front panel display and
Telnet.
When beginning a test from the front panel, you can monitor the progress, but
you cannot control the test with Telnet. If you start a test with Telnet, and

session and need to kill the Telnet session from the front panel.
The tests performed by the front panel and through Telnet are identical.
Because the front panel displays a two-line limit, more detailed test results are
displayed with Telnet.
