QWS3270 Terminal Session connection

I am trying to connect to Terminal session.
This IBM terminal is opened in QWS3270 application which connects to terminal.
When i check in installation directory of QWS3270 app, i can see only winhllapi.dll not EHLAPI.dll to be able to use terminal session activity (EHLLAPI option).

  • I tried using ‘UiPath Internal’ option with hostname and port but only blank screen though it is showing connected.
  • I tried using .WS script but no luck with error connecting.
  • i have read maximum of forum Q and A but got nothing specific.

Please suggest if anyone has used QWS3270 to connect to IBM Terminal.
