Hi Cheers for the reply..

Im using 4.1 and 1.0.. I had set the tcp ports to be different..!

What I think I had done wrong was I only had one system timer and was tring to use this for

both processors.. Duh!!

(one would clear the interrupt and the other would hang waiting for it!!)

I have just got copies of 4.2 and 1.1.. im going to have a play today to see what improvements

(I actually have 7 niosII's in my design so im hopping it will make things a little easier.)
