Programs accessing the screen buffer through control sequences may lose synchronization with the actual display so that many text mode programs have a redisplay everything command, often associated with the Ctrl-L key combination. The most popular standards for such control sequences are ANSI and VT100. Programs that display output on remote video terminals must issue special control sequences to manipulate the screen buffer. This way, the output seen on the screen could be sent directly to the printer maintaining the same format.ĭepending on the environment, the screen buffer can be directly addressable. This was an analogy of early mechanical printers which had fixed pitch.
#Text mode in aquamacs code
A typical example is the IBM code page 437 character set.Īn important characteristic of text mode programs is that they assume monospace fonts, where every character has the same width on screen, which allows them to easily maintain the vertical alignment when displaying semi-graphical characters. Many character sets used in text mode applications also contain a limited set of predefined semi-graphical characters usable for drawing boxes and other rudimentary graphics, which can be used to highlight the content or to simulate widget or control interface objects found in GUI programs. Text mode applications communicate with the user by using command-line interfaces and text user interfaces. Typically, the screen consists of a uniform rectangular grid of character cells, each of which contains one of the characters of a character set at the same time, contrasted to all points addressable (APA) mode or other kinds of computer graphics modes. Text mode is a computer display mode in which content is internally represented on a computer screen in terms of characters rather than individual pixels.
