Read/write were swapped in _FC_READ_AND_WRITE_REGISTERS. Closed by 49d6f4a.
Page 38 in the document Modbus_Application_Protocol_V1_1b.pdf:
6.17 23 (0x17) Read/Write Multiple registers
This function code performs a combination of one read operation
and one write operation in a single MODBUS transaction. The write
operation is performed before the read.
The unit test has been updated.
