The response is stored at dataset LocalDsNr in the master.
Note: Read remote messaging is only supported at the master because the response
is always sent to node address 0 (the master).

Follower point-to-point messaging

receiving a token from the master, a follower can send one dataset to another
follower with a follower point-to-point message. The target drive is specified using the
node address.
