What are the virtualterminal protocol that can run gum smoothly?

[NeveIsa]

I am trying to implement a virtual terminal for a OLED display connected to a micro controller and I would like to know what are the protocol that can run gum smoothly. I can write stuff to the OLED using a framebuffer and I want to eventually be able to display gum menus on the oled. I am not even sure if what I am asking is the right question here but please help me with pointers to how I could even get started.

Thank you very much.
