+The refinement discussed here so far, is implemented in the
+overall structure of the program:
+
+
+ Operations -------------X
+ Screen(s)
+ Protocol / |
+ Shell X------------X Emulation |
+ \ V
+ Widget
+ Events X------------------
+
+
+Part Application Protocol Data model Visualization
+ User Events
+
+Files TEShell.C TEmulation.C Screen.C TEWidget.C
+ TEVt102.C
+
+Types TEShell Emulation TEScreen TEWidget
+
+
+
+The abstract data type, in which the text is represented and
+manipulated by a set of operations is
+
+
+------------------------------------------------------------------
+
+On the first glance, the terminal consists of the following
+parts:
+
+- A screen to display characters to the user on a rectangular area.
+- A keyboard to accept the user keypresses.
+- A bidirectional serial connection, on which the application
+ sends the text to be displayed to the terminal and on which
+ the user's key pressed are forwarded to the application.
+- The application that actually run on the terminal.
+
+More formally our terminal model consists of
+- a character screen : a matrix [Lines,Columns] -> Character
+- a current visual pointer position (cursor).
+- a set of operations by which the screen can be manipulated
+- a set of events (mainly keystrokes)
+- two streams on which bytes are exchanged between the
+ application and the terminal which are used to communicate
+ the operations and events between the two end points.
+- an initial state.
+
+ 0 (columns) V--- Columns-1
+ +-----------------------+
+ | | 0
+ | text on |
+ | the screen |
+ | | (lines)
+ | |
+ | |
+ | | Lines-1
+ +-----------------------+
+
+
+For adressing purpose, we call the (columnNo,lineNo) pair a "position"
+
+- protocol == collection of operations and their encoding.
