You don't "create ports." You install or enable applications and/or
services that open posts programmatically. What exactly are you trying to
accomplish?
you will need to configure an application to listen on port 9100.
For example, you can configure IIS to listen on port 9100 instead of
port 80. Clients will then point their web browsers to port 9100 to
be able to view the web pages.
If you need any more help, please provide a more information about
what you wish to accomplish.
