CONFIRM Verb
CONFIRM Verb
The CONFIRM verb requests confirmation of receipt of data or completion of some
function. This verb flushes the buffer of data waiting to be sent (sending the data to the
remote TP) and requests an explicit confirmation from the remote TP when it has
received the data. CONFIRM completes when SNAX/APC receives a confirmation or
error reply from the remote TP.

CMR-REQ-TO-SEND-IND
This field indicates whether the remote TP issued a REQUEST-TO-SEND verb. If
the field contains the letter Y, REQUEST-TO-SEND notification was received from
the remote TP, which requests the local TP to enter the Receive state. The local TP
can use RECEIVE-AND-WAIT or PREPARE-TO-RECEIVE to enter the Receive
state when ready.
If the field contains the letter N, the remote TP did not issue a REQUEST-TO-SEND
verb.
