Frame construction
DIALOG MECHANISM (ASYNCHRONOUS LINK)
The Modbus RTU data frames do not include delimiters.
The synchronization is achieved by using a delay 3.5 times longer than the transmission time of a byte.
At the end of this delay, the first byte received is considered as the start of a new frame.
