<p>Use the <b>Toggle Breakpoint</b> command  (<span class="code">Ctrl+Shift+B</span>) to set a regular breakpoint in an <a href="PLUGINS_ROOT/org.eclipse.cdt.doc.user/reference/cdt_u_editor_view.htm">Editor</a>  or  <a href="../../reference/view_disassembly.htm">Disassembly</a> view. Only a single breakpoint can exist on a source code line. A regular breakpoint suspends program execution when it is hit, or executed, during a debug session. The debugger executes the line of source code that contains the regular breakpoint, then opens the <a href="../../reference/perspective_debug.htm">Debug</a> perspective to allow examination and modification.</p>

<p>If a regular breakpoint already exists on the  selected line, as indicated by the enabled breakpoint badge (<img src="../../tasks/breakpoints/images/breakpoints_enabled_icon.png" width="9" height="10" align="baseline">) in the marker bar,  use <b>Toggle Breakpoint</b> to remove the breakpoint.</p>

<p class="note"><strong>TIP</strong> If debugging a server launched by a client, you must attach to the server  process using the <a href="../../reference/view_symbian_kernel.htm">Symbian OS Data</a> view in order to hit the breakpoints in the server. Alternately, you can launch the server and  client as two independent EXEs using the same COM port and debug them that way.</p>
