Terminal Emulation

The user interface to CICS and IMS applications from the PC is often through 3270 terminal emulators. The 3270 terminal emulators enable the CICS and IMS applications to display input and output screens on the PC using 3270 data streams and to receive input from the PC. It is intended for programs that use BMS or build 3270 data streams. Emulation is provided for 3270 models 2 through 5.

We recommend that you use a Telnet 3270 (TN3270) client. The keyboard mapping and support for character level attributes is a property of the third-party TN3270 client you choose.

• This product's installation installs the Micro Focus Host Access for the Cloud (HACloud) terminal emulator.
• You can use other TN3270 emulators. For example, if you are a Micro Focus Rumba+ Desktop or a Micro Focus Reflection Desktop user, you can specify these emulators inside the IDE.

  In Enterprise Test Server you can use some special field types that are required by the 3270 sessions in Micro Focus Reflection Desktop and InfoConnect Desktop starting from version 17.0 Service Pack 1. See Working with Micro Focus Terminal Emulators.

When you start a 3270 terminal emulator, it is separate from the enterprise server region that runs the CICS or IMS application. Terminals do not need to be predefined. This means terminal emulation characteristics can be specified at terminal startup.

Enterprise Test Server needs to have a listener for requests from 3270 terminal emulators. You add this as part of configuring the enterprise server region that will run your CICS or IMS application.
