Jagacy is not listed as a supported terminal emulator in the UFT PAM document. I did some brief research on Jagacy, and it doesn't look like it has a hllapi.dll, so UFT is not going to be able to offer full object recognition like you would have with a supported emulator. With that being said, you should be able to follow the instructions in the UFT Addin guide under the Terminal Emulation section and configure UFT to work in text-only mode with it. It won't give you the full integration that you are seeking, but you should be able to test the data and still navigate through the emulator.
