IT27697: PCOM: PCSXFER041 TIMEOUT ON 3270 FILE TRANSFER WITH 27X132 SCREEN SIZE

IBM Personal Communications 13.0.2.1
IBM Personal Communications 12.0.4.2

APAR status

• Closed as program error.

Error description

• We are testing PCOMM V13 and several early testers are having a
  problem with the RECEIVE function.   The "Receive File Status"
  pops up and stalls until the session times out.
  
  They are doing the RECEIVE while in ISPF option 6 "ISPF Command
  Shell" under z/OS 2.3.   They say it used to work in PCOMM V6.
  
  PCOMM V13 RECEIVE works from the READY prompt.   Should it also
  work from the  "ISPF Command Shell"?
  
  We also tested PCOMM 13.0.2 (the latest available) and have the
  same problem.
  
  Mod5 and OPT 0 set to data does not work.
  Mod5 and OPT 0 set to std works.
  Mod5 and OPT 0 set to max works.
  
  Mod2 and OPT 0 set to data works.
  Mod2 and OPT 0 set to std works.
  Mod2 and OPT 0 set to max works.

• This issue is caused by thread synchronization failure post
  Microsoft Creators updates for Windows 10 OS. PCSXFER.DLL has
  been changed to remove thread synchronization as Microsoft
  Windows handles the required logic.
  
  Fix is scheduled for PCOMM 13.0.2.1 and 12.0.4.2 Fix Packs
