8 Character Cell Graphics

This chapter deals with screen input and output that is not pixel based, but character based. When we say character, we mean a composition of pixels that can be changed depending on a charset. Your graphic card already offers one or more charsets and operates by default in text (charset) mode because text can be processed much faster than pixel graphic. There is more to do with terminals than to use them as simple (dumb) and boring text displays. I will describe how to use the special features that your linux terminal, especially the linux console, offers.

In the following sections I will describe how to use the different packages to access a terminal. With Linux we have the GNU-version of termcap and we can use ncurses instead of curses.
