Connect (TCP) Test
When in Continuous mode, the test's results are shown on the
RESULTS tab. The test is not graded as having passed or failed
until the test is stopped. Press the AutoTest key to stop

the test.
Proxy - The Proxy control lets you specify a proxy server through
which the TCP connection will be established. To specify a proxy
server, tap the Proxy button, tap On, and set the server's address
and port. Otherwise, continue to the next step.

How it Works

The TCP test performs a DNS lookup on the specified URL. If you
specify an IP address, the DNS lookup is not performed.
The TCP connection is established by executing a three-way
handshake (SYN, SYN/ACK, ACK). At this point the test is
complete and the analyzer closes the port. No data is transferred
after the TCP connection is established.
If you have set the count to a number greater than one, the TCP
connection process is repeated.
