I have built a client for Matlab using the text-mode protocol and most of it seems to work fine:

1. Establishing a connection to lightstreamer server works (I receive a sessionId)
2. Subscribing/unsubscribing works (http response is 200/OK)

But my problem is that the subscription should already invoke the streaming of the data. How can I access it?

When I paste the URL query of the request into a webbrowser I get the message "SYNC ERROR" but that might be due to the missing headers in this case.

I am using the urlead2 function to send/receive the http requests. Underneath it is JAVA afterall. Maybe I need to add some kind of listener here?

Can anybody give me a hint please?
