What does the Pass Mode (session) Option do in CA-TPX Session Management?
You can set up an application session to be a PASS session (PASS = Y in profile-level or user-level session definition) so that when a user selects the session, CA TPX "passes" the physical terminal to the session.
The application communicates directly with the physical terminal as if a session manager is not in use. While in PASS mode for the application session, CA TPX functions, such as toggling between sessions, are unavailable. When the application session is terminated, CA TPX regains control of the physical terminal.
