Right. That's what I thought originally.<br>
<p>
I _think_ the VMware guys are still planning on using ppdev proper at some<br>
stage in the future.<br>
<p>
If not, perhaps the FreeMware folks will..<br>

<i>&gt; Is it possible to make software emulation of the PC port (at different</i><br>

<p>
You'd have to do exactly the same tricks that VMware does.<br>
