In a one-way conversation with confirm, the side that sends
the data requests confirmation from the receiving side that the
conversation is synchronized. Figure 2-2 “One-Way Phone Conversation With Confirm” illustrates
a one-way conversation in which the local TP asks the remote TP
for confirmation that it received all the data the local TP sent.
In a one-way conversation with confirm, the caller does not
hang up until it has received confirmation that the conversation
is synchronized. Once synchronization has been confirmed, each side
ends the conversation independently of the other.
