+<h2>5. Debug and Error Messages</h2>
+<p>
+Generation of debug and error messages is controlled with two shell variables,
+<code>streamDebug</code> and <code>streamError</code>.
+Setting those variables to 1 (actually to any number but 0) enables the
+messages.
+Per default debug messages are switched off and error messages are switched on.
+Errors occuring while loading protocol files are always shown.
+</p>
+<p>
+Warning: Enabling debug messages can create a lot of output!
+At the moment, there is no way to set filters on debug or error messages.
+</p>
+<p>
+Debug output can be redirected to a file with the command
+<code>streamSetLogfile("<var>filename</var>")</code>.
+When called without a filename, debug output is directed back
+to the console.
+</p>
+
+<h3>Example (vxWorks):</h3>
+<pre>
+streamError=1
+streamDebug=1
