The implied use for data is to echo it. Julo

BTW, What is the reason for a Target Ping not to carry any data?

Julian,
you are of course correct.  My implied (though perhaps not so well written)
point was that a ping INITIATED by the target, is also possible, but can
not have data.  And that the removal of the word "ping" would perhaps
prevent that concept from being obvious.

John.

Ping from target is prohibited from having data only if  TTT is 0xfffffffff
i.e., when no reply request is requested.

You may be correct, but I think we need to use the Ping word, so that it
becomes obvious, as it does now, that Ping from Initiator can have data but
ping from Target can not.
