<listitem>Displays the number of microseconds it takes to
get a reply on a ping to to tcp 'port' on 'host'. 'port' is optional
and has 54321 as default. This works on both open and closed
ports, just make sure that the port is not behind a firewall or you
will get 'down' as answer. It's best to test a closed port instead
of an open port, you will get a quicker response.
