Problem with concurrent sending and receiving data with ethernet

Hi,

I'm working with the Simple Socket Server example for my DE4-230 board (that is...blinking Leds and 7segments display example....). I modified this example simply adding a" while (stop==1)...etc etc" to send random 32bit data to pc when nios system receives a command (an ASCII character 'L') from my client Labwindows program. These 32 bit data are effectively received continuously but when I try to send from Labwindows another command (i.e: those for managing blinking Leds or socket closing...) it seems that communication towards nios II is blocked...and so the loop data receiving is unstoppable...

Any Ideas??

regards

    Lean back an think what you are doing. Without escaping the loop, the server won't handle any new commands, isn't it?

    yes...It is....I know that...but I don't know as I could do this kind of operation (I mean... this loop data sending controlling its starting and stopping from pc) I tried also to create a new task in which there is this "while(stop==0)" with a fixed priority, I tried to delayed the task execution to allow processor to execute other tasks...but the situation was the same!!!...
