Reserving a part of console using assembly language in X86_32 Linux

I'm developing a text editor like VI with assembly and need to take control of console, exactly like Vi, for example changing the position of cursor and inserting and deleting of strings. I googled a lot but did开发者_开发技巧n't find any good suggestion, the code is not my problem, I want to get the idea of how to do it, then i could code it myself I'm using NASM and 32 bit Linux OS.

Look into sources of curses library (ncurses(3)) and see how Unix terminals are manipulated.
