The Full-Duplex SIG had its meeting at the June CIW on June 9, 1993.
The document "Mapping CPI-C Full-duplex Communications (2.x) onto
OSI Distributed Transaction Processing" was discussed. There was
consensus within the SIG for the proposed enhancements to CPIC FDX to
enable a complete mapping from/to OSI TP Shared Control; there was
also consensus within the SIG on the actual mapping of CPIC FDX to/from
OSI TP.

The above-named document dated May 24, with the following proposed
changes since May 24, was given AD within the FDX SIG:
- CM_DEALLOCATED_ABEND with secondary return code
  DEALLOC_CONFIRM_COLLISION and
  CM_DEALLOCATED_ABEND with secondary return code
  BEGIN_TRANSACTION_COLLISION will be returned instead of
  CM_DEALLOC_CONFIRM_COLLISION and CM_BEGIN_TRANSACTION_COLLISION,
  respectively.
- CM_DEALLOCATED_ABEND_BO with secondary return code
  DEALLOC_CONFIRM_COLLISION will be returned instead of
  CM_DEALLOC_CONFIRM_COLLISION_BO.
- RTS_or_exp_data_received is renamed control_info_received.

The FDX SIG also briefly examined the changes to the document
"CPI-C Full-duplex Conversations and Expedited Data" which was
granted AD status for the enhancements and mapping for APPC
in March 1993. The changes were approved with the following
correction/enhancements:-
- The call Extract_Partner_Id being proposed by the Directory SIG
  will be used instead of Extract_Partner_Binding to determine the
  the CRM type that is being used with the partner. This information
  is required to know the purging behavior when CMSERR is issued.
- Calls such as CMCFM, CMPTR, CMRTS, CMTRTS, CMSPRT, and CMSED
  that get CM_PROGRAM_PARAMETER_CHECK when the send_receive_mode
  has been set to CM_FULL_DUPLEX, can extract a secondary return code
  which will have the value such as INAPPLICABLE_CALL.

The FDX SIG requested AD on the CPIC FDX enhancements for OSI TP, and
on the CPIC FDX mapping to/from OSI TP (except the Handshake FU which
will not being included at this time). The CIW granted this request
at the closing plenary sesion on June 11.
This status change, in conjunction with the AD for the APPC enhancements
and mapping granted in March, completes AD status for the CPIC FDX
proposal.
The FDX SIG aims at getting AP status at the September CIW. Stay tuned.

Cordially yours,
