    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
    None.
    
    MIGRATION CONSIDERATIONS: NO
    None.
