Error description

• FOR LUTYPE1 AND LUTYPE 3 PRINTERS, BID REJECTS (0813) CAN OCCUR
  IF AN APPLICATION RUNNING UNDER CICS WAS PRINTING TO A 3270 C/U
  PRINTER THAT WAS POWERED OFF. SENSE0831 IS RETURNED TO THE HOST
  TO INDICATE THIS CONDITION.  AFTER POWERING THE DEVICE BACK ON,
  CICS SHOULD SEND A NEW BID BEFORE SENDING THE NEW DATASTREAM,
  BUT THIS WAS REJECTED WITH SENSE0813, BECAUSE THE CONTROL UNIT
  STILL HAD THE PRINTER IN BRACKET STATE.
  
  THE SESSION WAS BOUND WITH EXCEPTION RESPONSE ONLY (ER1).
  INSTEAD OF DEFINITE RESPONSE (DR1).  WHEN CICS SENT THE FIRST
  DATASTREAM, IT WAS A MULTIPLE RU CHAIN WITH THE END BRACKET
  (EB) ON THE LAST RU.  CICS THEN RESET THE INTERNAL STATE TO
  RECEIVE TO INDICATE BETWEEN BRACKETS (BETB).  THE CONTROL UNIT
  WAITED TILL ALL THE DATA WAS RECEIVED BEFORE SENDING IN THE
  POWER OFF INDICATION, AND FAILED TO RESET THE STATE TO BETB
  FOR THE PRINTER.  THUS THE DATA IS LOST AS WELL AS THE EB
  INDICATION.
  
  LATER, WHEN THE PRINTER IS POWERED BACK UP, CICS SENDS A NEW
  BID, WHICH IS REJECTED WITH SENSE0813 INDICATING A BRACKET STATE
  ERROR SINCE THE DEVICE IS NOT IN THE BETB BRACKET STATE WHEN
  THE BID WITH BEGIN BRACKET (BB) IS SENT FROM CICS.
  
  DATA SENT LAST IN CHAIN (LIC) OR ONLY IN CHAIN (OIC) RQE1 WILL
  OBSERVE BRACKET TERMINATION RULE 1 TO END BRACKET.  THIS RULE
  REQUIRES THE DEVICE TO RESET THE BETB BRACKET STATE, WHICH DID
  NOT OCCUR. PL36403 DOCUMENTS THIS REQUIREMENT.
  
  THIS PROBLEM CAN BE PREVENTED FOR LUTYPE1 OR LUTYPE3 PRINTERS
  USING DR1 DEFINITE RESPONSE MODE FOR APPLICATIONS USING THESE
  PRINTERS.  THIS IS SET BY CODING THE MESSAGE INTERGRITY OPTION
  ON THE PCT DEFINTION (REFERENCE THE RESOUCE DEFINITION MANUAL).
  THE PROBLEM IS LIMITED TO SNA LUTYPE1 AND LUTYPE3 PRINTERS.
  LUTYPE0 FORCES THE USE OF OF DR1.
  
  THE BEST SOLUTION FOR THE PROBLEM, AS DEFINED BY BOTH CICS
  DEVELOPMENT AND HARDWARE DEVELOPMENT IS TO USE DEFINITE
  RESPONSE MODE IN SUCH ENVIRONMENTS WHERE MESSAGE INTEGRITY IS
  NECESSARY.  DEVICES WHICH FAIL TO RESET THE BRACKET STATE TO
  BETB UNDER THESE CONDITIONS SHOULD DOCUMENT THIS FACT IN THE
  APPROPRIATE MANUALS.  IT SHOULD ALSO INDICATE THE DEFINITE
  RESPONSE MODE IS REQUIRED.
