MC-RECEIVE-IMMEDIATE Verb
MC-RI-MAX-DATA-LENGTH,
specifies the maximum amount of data that the local TP can receive in one reply.
The value specified here must be such that the size of the reply from SNAX/APC is
less than or equal to the size specified in MAXAPPLIOSIZE when SNAX/APC was
started.
Reply Details
The MC-RECEIVE-IMMEDIATE verb reply has four parameters in addition to the
standard SNAX/APC reply header.
RESERVED-1
is reserved, and must contain either a 0 or a space (ASCII 32).
MC-RIR-REQUEST-TO-SEND-IND
indicates whether or not the remote TP issued a REQUEST-TO-SEND verb. It must
contain either a “Y” or an “N”.
MC-RIR-WHAT-RECEIVED
indicates what was received from the remote TP, and must contain a number
between 1 and 6, as specified in the DDL definition of the Reply Format.
MC-WR-DATA-COMPLETE (1)
The local TP received a complete logical record or the last remaining portion of
a logical record.
MC-WR-DATA-INCOMPLETE (2)
The local TP received an incomplete logical record (because the logical record
was longer than RI-MAX-DATA-LENGTH). The local TP should issue another
MC-RECEIVE-IMMEDIATE (or MC-RECEIVE-AND-WAIT) verb to receive
the remainder of the logical record.
MC-WR-SEND (3)
The remote TP entered the Receive state, thereby placing the local TP in the
Send state. No data is received in this reply. The local TP can now issue MC-
SEND-DATA verbs.
MC-WR-CONFIRM (4)
The remote TP issued an MC-CONFIRM verb. The local TP enters Confirm
state and can respond by issuing either MC-CONFIRMED or MC-SEND-
ERROR. No data is received in this reply.
MC-WR-CONFIRM-SEND (5)
The remote TP issued an MC-PREPARE-TO-RECEIVE verb either with
CONFIRM or with SYNC-LEVEL, and the synchronization level is CONFIRM.
