Screen control mode terminal connects to a TOR and application runs in an AOR

In this scenario, the user starts the DTSC transaction on the display terminal to display the debug session. DTSC must run in the same region as the application, but could run in any of the following situations:

• As a Transaction-Routed transaction
• On a CRTE terminal session which was started on the AOR
