title: Access parallel port using Linux
body: <p>currently I access the parallel port this way:</p>
  
  <pre><code>ioperm(data-&gt;baseaddr,5,1);
  outb(0x00,data-&gt;controlport);
  inb(data-&gt;statusport);
  </code></pre>
  
  <p>The big disadvantage: it requires root-privileges and works with real parallel port hardware only (means USB-2-LPT converters are not supported).</p>
  
  <p>So: is there an other way tho read/write data from/to parallel port?</p>
  
  <p>Thanks!</p>
