Some notable programs of this kind were Microsoft Word, DOS Shell, WordPerfect, Norton Commander, Turbo Vision based Borland Turbo Pascal and Turbo C (the latter included the conio library), Lotus 1-2-3 and many others. Soon mouse input was added – either at text resolution as a simple colored box or at graphical resolution thanks to the ability of the Enhanced Graphics Adapter (EGA) and Video Graphics Array (VGA) display adapters to redefine the text character shapes by software – providing additional functions. Later, the interface became deeply influenced by graphical user interfaces (GUI), adding pull-down menus, overlapping windows, dialog boxes and GUI widgets operated by mnemonics or keyboard shortcuts. Most often those programs used a blue background for the main screen, with white or yellow characters, although commonly they had also user color customization. A more precise cursor (per-pixel resolution) was achieved by regenerating the glyphs of characters used where the cursor was visible, at each mouse movement in real-time. However, not all terminals follow this standard, and many non-compatible but functionally equivalent sequences exist. Escape sequences may be supported for all three cases mentioned in the above section, allowing random cursor movements and color changes. On ANSI-compatible terminalsĪmerican National Standards Institute (ANSI) standard ANSI X3.64 defines a standard set of escape sequences that can be used to drive terminals to create TUIs (see ANSI escape code). Also, specialized programming libraries help to output the text in a way appropriate to the given display device and interface to it. Under Linux and other Unix-like systems, a program easily accommodates to any of three cases because the same interface (namely, standard streams) is used to control the display and keyboard.

This is the worst case, because software restrictions hinder the use of capabilities of a remote display device.

The communication capabilities usually become reduced to a serial line or its emulation, possibly with few ioctl()s as an out-of-band channel in such cases as Telnet and Secure Shell. Certain functions of an advanced text mode, such as an own font uploading, almost certainly become unavailable. This usually supports programs which expect a real text mode display, but may run considerably slower. Examples are xterm for X Window System and win32 console (in a window mode) for Microsoft Windows.

If not deterred by the operating system, a smart program may exploit the full power of a hardware text mode. This is a normal condition for a locally-running application on various types of personal computers and mobile devices.
