Two specific receives become incorrect when using the SerialPort class. Example: 'xx xx xx xx 27 AD ff ff 4a' becomes 'xx xx xx xx xx 27 7D 52 ff ff 4a'. The correct value would have been AD, which is now received as 7D 52, but I found that the inverse of 52 is AD. May I ask what is the cause of this
