frame data.
RTU mode
：
two bytes of 16 hex
The CRC domain is two bytes, including a binary value of 16 bits. It is calculated and added
to the message by the sending end; while low byte added in front, and high byte added in
post then, so the high byte of CRC is the last of the message. The receiving device
re-calculates the CRC of the message, and compares it with the CRC in receiving domain, if
the two values are different, it means there is error in received message, and the message
frame is discarded, while there is no responding but waiting for the next frame data. CRC
checksum calculation method reference to MODBUS protocol specification.
