External Presentation Interface (EPI)

The External Presentation Interface (EPI) enables a user application to install a virtual IBM® 3270 terminal into a CICS® server. The EPI also enables a user application to delete a virtual IBM 3270 terminal from a CICS server.

The 3270 terminal definitions used by the EPI are treated by CICS servers as remote 3270 terminal definitions and therefore support automatic transaction initiation requests (ATI). For more information on ATI see the CICS Application Programming Guide.
