ReadHoldingRegisters #14

So I hope that somebody has gone though the same issue as me; I'm trying to obtain the content of a holding register through the serial port. I can see the content but it's not understandable. What I'm getting It's not ASCII or any other variable type. resute = node.readHoldingRegisters(25, 6);

If your ModbusIP object is called mb: int16_t value = mb.Hreg(offset);
