(*) appears on the screen every quarter second. If the VersiPort is not detecting an active
signal, a dash (-) appears on the screen at quarter second intervals. An active signal is defined
by a contact closure to ground or TTL logic "0". Inactive signals are defined as open or TTL logic
"1". To end the test, depress the space bar.
