+    configuration, <code>Target options</code>, enable <code>Generic
+    serial port config</code>, and select the serial port and speed
+    you would like to use for the shell. This will automatically tune
+    the <code>/etc/inittab</code> file of the generated system so that
+    a shell starts on the correct serial port.</p>
