Hallo Vladimir,

thanks for your answer. The reason that overlapped/none-overlapped is't good, is that we need to synchronize on a break between 2 recived packet, the break is 200uS.
I have used the "API" way of communication, and for normaly applications it works perfektly. But in this case it's to slow.
