Hi Vlad,

I already tried it, but unfortunatelly it has same behavior...it is not 
possible to stop the client process, beacuese it is never started (???). But 
I really don't understand why say "ok,Pid" result when I create the cleint. 
I think I have a big mistake now....
I already read the documentation, but...it is not enough...for me :-(

I did that, what is in the documentation in the dbg side step-by-step, but 
it doesn't works for me...:-(((

thanks a lot for your advice,

regards,
/Robi
