title: Can't turn off unconnected-port warnings in simulink using Matlab R2010b 7.11.2
body: <p>My model has a lot of unconnected Input and Output ports, which I don't mind. So I tried turning those annoying warnings like</p>
  <blockquote>
  <p>Warning: Output port 3 of 'Model_ESM_6/L-ESM-6/Wankdynamik' is not
  connected.</p>
  <blockquote>
  <p>In ESM6_resim at 1</p>
  </blockquote>
  </blockquote>
  <p>off. I went to simulink preferences -&gt; Diagnostics -&gt; connectivity and then I set &quot;unconnected block Output/Input ports&quot; to &quot;None&quot;. Another Simulation showed, that this had no effect. What am I doing wrong?</p>
