  ABSTRACT:
  Allow 3270 local devices that are permanently logged into SMP

  COMMENTS:
  An enhancement has been created to allow 3270 local devices
  that are permanently logged into SMP to be stopped and
  restarted using the ZLSTP and ZLSTA commands. Prior to this
  enhancement, the ZLSTP command could not be used to stop a 3270
  local terminal logged to SMP, due to the fact that the terminal
  was permanently logged to an application. As a result,
  permanently logged terminals could not be stopped and restarted
  in order to perform hardware maintenance on the device.
  

Problem conclusion

• SOLUTION:
  An enhancement has been made to real-time segments cvlg.asm
  (ZLSTP processing) and cvlc.asm (ZLSTA processing) to allow the
  ZLSTP and ZLSTA commands to stop and restart a 3270 local line
  that is defined as permanently logged in its WGTA entry. CVLG
  has been changed to check to see if the 3270 local terminal is
  permanently logged, and then bypass the check to see if the ANT
  index in the WGTA is nonzero. Additionally, an indicator is set
  in the device CCW area in order for CVLC to set the "logged to
  SMP" bit in the device CCW area.
  
  COREQS: NO
