Kodi Notifications to external windows app

I am creating a small app to control Kodi. I am using VB6.
I have found on the internet that i can receive notifications
by using TCP from my app.
I am using the winsock control to connect and listen to port 9090
(if this is correct port) but i dont seems to get any data being returned.

What exactly do i need to do to receive notifications.

Any help will be appreciated.
