The user should wait for the prompt and input the ping6 command followed by the destination IPv6 address. The address should not use any abbreviated form (the application does very little input format check).
E.g. of a correct command:
> ping6 fe80:0000:0000:0000:02bd:07ff:fee2:1c00
The ping6 application will then send PING6_NB = 5 ping request packets.
