How to create a session that connects to an MVS ICC console

By default, a Flex Terminal Emulator session configured for standard mainframe 3270 Model 2 will negotiate with the host using a device type of IBM-3278-2-E. However, a console session is typically expecting a different device type, such as IBM-3277-2-E and you must customize the connection setup to accommodate this. Otherwise, the negotiation with the host will fail and you will receive an error such as TCP TN3270E Device Type Rejected RC=6.

Configure a custom device type using Advanced>Device Type Override:

  1. Open the Flex Terminal Emulator Workspace with the appropriate console session added.
  2. Make sure the session is disconnected, otherwise click the Connect button to toggle it to disconnected (background should be gray with white tex.)
  3. Click the Setup button.
  4. Locate and expand the Advanced section.
  5. In the Device Type Override field, enter the desired device type to negotiate with the host, for example IBM-3277-2-E.
  6. Click the Connect button to test the connection to the host using the new setting.
