Press the Enter button when you have typed the device address or FQDN. The phone first
resolves an FQDN. While it is resolving the address, the phone displays:

the name, the phone displays:
Press the Menu, Esc, or Enter buttons to exit this state.
If you typed an IP address, or an FDQN that was resolved, the ZIP4x4 sends up to 99 messages
to the host, each one second apart. Each message has 24 bytes of optional data (so the total
message length is 32 bytes) and the phone increments the sequence numbers starting with 0 after
power on and continuing to increment the numbers until 64K. The phone displays:
On the top row the phone displays the IP address of the host (which may be resolved from what
you typed). On the second row, the phone displays the number of the message (1 to 99), whether
it received a reply or not and the round trip delay. The phone calculates the round trip delay by
storing the time at which it sent the message in the data portion of the ICMP message. The phone
resolves this time to 10 ms.
On the bottom row, the phone displays the minimum, average, and maximum times of the round
trip delay, each in ms. This is resolved to 1 ms.
The maximum time that the phone waits for a response is 990 ms. If it receives a response after
that time, it ignores it. After this time-out, the phone displays:
The phone does not count this time to calculate the minimum, average, or maximum times.
