+      NxConsole supports caching of rendered fonts.
+      This font caching is required for two reasons:
+      (1) First, it improves text performance, but more importantly
+      (2) it preserves the font memory.
+      Since the NX server runs on a separate server thread, it requires that the rendered font memory persist until the server has a chance to render the font.
+      Unfortunately, the font cache would be quite large if all fonts were saved.
+      The <code>CONFIG_NXCONSOLE_CACHESIZE</code> setting will control the size of the font cache (in number of glyphs).
+      Only that number of the most recently used glyphs will be retained.
+      Default: 16.
+      <blockquote>
+        NOTE: There can still be a race condition between the NxConsole driver and the
+        NX task.  If you every see character corruption (especially when printing
+        a lot of data or scrolling), then increasing the value of <code>CONFIG_NXCONSOLE_CACHESIZE</code>
+        is something that you should try.
+        Alternatively, you can reduce the size of <code>CONFIG_MQ_MAXMSGSIZE</code> which will force NxConsole task to pace the server task.
+        <code>CONFIG_NXCONSOLE_CACHESIZE</code> should be larger than <code>CONFIG_MQ_MAXMSGSIZE</code> in any event.
