2.
H <- E S2F44
The Equipment enables spooling for the messages requested by the Host.
Response has RSPACK set to zero as follows:
S2F44
<L [2]
<B [1] 00> * RSPACK
<L>
> .
7.9.2 Messages Spooled and Transmitted
Assumption: Spool State is "Spool Inactive".
Step SECS Message Description
1. H <- E SnFn Equipment attempts to send any message to the Host.
2.
After failure to deliver message, the Equipment assumes that the link is down,
and will start to spool all messages marked for spooling. The first message
spooled is the collection event "SpoolActivated".
3.
H <- E S1F13 W
Equipment attempts to establish communications. This message will repeat
every "EstablishCommunicationsTimer" seconds until successful.
4.
H -> E S1F14
Communications established. Communications state transits to
"Communicating". If COMMACK is not zero, communications are not
established and scenario proceeds at step 3.
5.
H -> E S6F23 W
Host requests that Equipment begin despooling messages. RSDC is zero in
this message.
6.
H <- E S6F24
Equipment indicates that it will start to send spooled messages with return
code RSDA = 0x00.
7.
Equipment will start to despool messages. This process is single-threaded.
That is, when Equipment sends a de- spooled message with the W-bit set to
"1", Equipment must be receive the Host reply before the equipment will send
next despooled message. If EC "MaxSpoolTransmit" is zero, all messages
will be transmitted. If it is set to another number, this number of messages
will be sent. The Equipment will await the next S6F23 to send the next
messages.
8.
H <- E S6F11 W
The Equipment signals CEID GemSpoolActivated. This was the first
message in the spool if it was not over-written.
9. H -> E S6F12 Host acknowledges the start of the spool transfer.
10.
Equipment will de-spool messages one at a time from oldest to youngest until
one of the following criteria is met: 1) All messages have been transmitted
(go to step 13); or 2) When "MaxSpoolTransmit" is not zero, and the
messages transmitted has reached MaxSpoolTransmit limit (go to step 11).
Some spooled messages (usually multi-block) consist of a SECS
conversation of type "Inquire, Grant, Send, Acknowledge". During de-spool,
if the Host rejects the Inquire, the multi-block message is removed from the
spool and not transmitted. Despooling continues.
11. H -> E S6F23 W The Host requests that the Equipment continue de-spooling messages.
12.
H <- E S6F24
Equipment indicates that it will start to send spooled messages with return
code RSDA = 0x00. Go to step10.
13.
H <- E S6F11 W
Equipment notifies the Host that sending of spooled messages has been
completed by sending CEID GemSpooling Deactivated.
14. H -> E S6F12 Host acknowledges that the spool has been cleared and is deactivated.
