  20    <p>The TUI has two display modes that can be switched while
  21 GDB runs:
  22
  23      <ul>
  24 <li>A curses (or TUI) mode in which it displays several text
  25 windows on the terminal.
  26
  27      <li>A standard mode which corresponds to the GDB configured without
  28 the TUI.
  29 </ul>
  30
  31    <p>In the TUI mode, GDB can display several text window
  32 on the terminal:
  33
  34      <dl>
  35 <dt><em>command</em>
  36      <dd>This window is the GDB command window with the GDB
  37 prompt and the GDB outputs.  The GDB input is still
  38 managed using readline but through the TUI.  The <em>command</em>
  39 window is always visible.
  40
  41      <br><dt><em>source</em>
  42      <dd>The source window shows the source file of the program.  The current
  43 line as well as active breakpoints are displayed in this window.
  44 The current program position is shown with the <code>&gt;</code> marker and
  45 active breakpoints are shown with <code>*</code> markers.
  46
  47      <br><dt><em>assembly</em>
  48      <dd>The assembly window shows the disassembly output of the program.
  49
  50      <br><dt><em>register</em>
  51      <dd>This window shows the processor registers.  It detects when
  52 a register is changed and when this is the case, registers that have
  53 changed are highlighted.
  54
  55    </dl>
  56
  57    <p>The source, assembly and register windows are attached to the thread
  58 and the frame position.  They are updated when the current thread
  59 changes, when the frame changes or when the program counter changes.
  60 These three windows are arranged by the TUI according to several
  61 layouts.  The layout defines which of these three windows are visible.
  62 The following layouts are available:
  63
  64      <ul>
  65 <li>source
  66
  67      <li>assembly
  68
  69      <li>source and assembly
  70
  71      <li>source and registers
  72
  73      <li>assembly and registers
  74
  75    </ul>
