As I understand it, the IBM 3270 was a completely different type of terminal than we normally use with Unix.
Imagine you are an airline or a bank, with thousands of employees all connected to a central mainframe. You do not want to interrupt the computer every time a user presses a key, which is what would would happen with serial terminals, and with SSH. You send a full page of information and questions at once, and the user fills in fields locally on their terminal, then submits the page as a single request.
apt search 3270 finds several related packages in Debian/Raspbian. I suspect they emulate the client, not the mainframe.
The modern equivalent would be to build a web interface, using either HTML Forms or client-side JavaScript.
