How can I tell my Windows Service to use port 81?

ServiceStack Self Hosting

I am running on Windows 8.1 Enterprise, with a web site running (IIS 8.5). It seems that ServiceStack uses port 80 by default for a Windows Service. Could you please show me some code that will cause my Windows Service to use port 81 instead.

Thanks

Should just be a matter of changing this url to use port 81:

class Program
{
    private const string ListeningOn = "http://localhost:81/";
}
