The instruction I sent was：01 03 fa 0c 00 01 74 d1 should respond：01 03 00 02 13 8C E8 9F The runner finds that the sending is correct, but the data of the response is missing a bit The program sends instructions： b'\x01\x03\xfa\x0c\x00\x01t\xd1'（01 03 fa 0c 00 01 74 d1），Program response：b'\x01\x03\x00\x02\x13\x8c\xe8'（01 03 00 02 13 8C E8） I've noticed that when it counts the number of bits of response data, it's one bit less. The correct one should be 8 bits, and it calculates 7 bits Eventually returned：ModbusIOException('[Input/Output] No Response received from the remote slave/Unable to decode response') I'm using serial access, and I make sure that all parameters are correct, such as baud rate. How can I fix it
self.client = ModbusSerialClient(port=port, baudrate=baudrate, timeout=timeout)
self.client.connect()
result = self.client.read_holding_registers(slave=self.slave, address=starting_address)
