when testing telnet, if the IW application is not loaded, then
telnet localhost 21401
Connecting to localhost...Could not open a connection to this node, on port 21401: Connection failed
If the IW application is loaded, then :
Black screen. When you press Esc, the message :
HTTP/1.1 400 Bad Request
Content-Type: text/html; charset=us-ascii
Server: Microsoft-HTTPAPI/2.0

<BODY><h2>Bad Request - Invalid Verb</h2>
<hr><p>HTTP Error 400. The request verb is invalid.</p>
</BODY></HTML>
From this I conclude that the port is used only by my IW application.
