amindzo, You should use the "WAIT" qualifier in your hserin statement and then make the qualifier string something like the word "data" and then send the data bytes. Your receiver's data slicer is probably decoding noise and this noise is being interpreted by the UART as data bytes. The qualifier used in the hserin statement will WAIT for the qualifier string (in this case "data") to br received before receiving any further bytes. It's in the manual.....
