Jo (VIP) Hy there, i have the problem concerning the serial communication. First i have to send 30 Bytes with 50Baud to a client. After that, the client returns me 3 Bytes with 9600 Baud. The client does this reflection within 200ms after complete receiving that 30 Bytes. So my problem is to switch my Baudrate from50 Baud to 9600 Baud within those 200 ms (150ms to have security). I did not manage this till now. Is that possible with Windows SDK?
