Hi Dane,
Take a look at the Documents section of the BP Portal and search for 'attachmate' or 'mainframe'. There are a few pieces of documentation that should help if you're looking for the significance of those inputs. But basically what is required for those inputs can be found in the configuration of the emulator that you're using.
For example, in these docs below, there are screenshots of the configuration (not sure what variant you're using so you'll have to look into that) of the indicated attachmate variant:
Blueprism Mainframe Guide - Attachmate InfoConnect
Blueprism Mainframe Guide - Micro Focus Attachmate Extra
Respectfully,
Dave
