Plan 9 is built as a text first graphical system without any text terminal protocols. Like Unix it has a command line but it's just a typewriter, you cant control the cursor. Instead you have draw(3) which serves the graphical facilities of a system which you load assets into and issue draw commands to manipulate and display them. Of course to maintain backwards compatibility there is vt(1) which is a graphical program that transparently gives you a vt-100 or 220 display.
