-    \title Using libmodbus Backend
-
-    \brief Overview of how to use the libmodbus backend.
-
-    Libmodbus is a free software library to send/receive data according to the Modbus protocol.
-    Libmodbus only supports TCP and serial port connections.
-
-    \section1 Creating Modbus Devices
-
-    At first it is necessary to check that QModbus provides the desired backend:
-
-    \code
-        foreach (const QByteArray &backend, QCanBus::instance()->plugins()) {
-            if (backend == "libmodbus") {
-                // were found
-                break;
-            }
-        }
-    \endcode
-
-    Where, \e libmodbus is the backend name.
-
-    Further, it is necessary to request from QModbus the device with the active libmodbus
-    interface.
-    As libmodbus device may be either client or server device, you have to choose between
-    QModbus::createServer() and QModbus::createClient() as appropriate:
-
-    \code
-        QModbusServer *server = QModbus::createServer("libmodbus");
-    \endcode
-
-    or
-
-    \code
-        QModbusClient *client = QModbus::createClient("libmodbus");
-    \endcode
-
-    For every server, tables must be initialized before connecting it to the network.
-    Next example will set up every table to be size of ten values. Maps can also
-    be not set at all, in that case they will be size zero. Value of every field is
-    initialized to zero.
-
-    \code
-        modbusServer->setMap(QModbusDevice::DiscreteInputs, 10);
-        modbusServer->setMap(QModbusDevice::Coils, 10);
-        modbusServer->setMap(QModbusDevice::InputRegisters, 10);
-        modbusServer->setMap(QModbusDevice::HoldingRegisters, 10);
-    \endcode
-
-    Before connection each device must also be given a connection to the network.
-    Remember that libmodbus only supports serial port and tcp. Application data unit (ADU)
-    is the package type specified for the connection type. Generally serial port uses
-    QModbusDevice::RemoteTerminalUnit adu and tcp uses QModbusDevice::TCP adu.
-
-    \code
-        QSerialPort *serialPort = new QSerialPort("ttyS0");
-        modbusServer->setDevice(serialPort, QModbusDevice::RemoteTerminalUnit)
-        modbusServer->setSlaveId(1);
-        modbusServer->connectDevice();
-    \endcode
-
-    Reading and writing with a client device can be done either with single field at once
-    or by bigger block of adjacent fields. If you try to read/write a list of QModbusDataUnits
-    that are not adjacent to each other read/write will be unsuccessful.
-
-    \code
-        QList<QModbusDataUnit> units;
-        units.append(QModbusDataUnit(QModbusDevice::HoldingRegisters, 3, 0x1af5));
-        units.append(QModbusDataUnit(QModbusDevice::HoldingRegisters, 4, 0x1001));
-        units.append(QModbusDataUnit(QModbusDevice::HoldingRegisters, 5, 0xff34));
-        modbusClient->write(units);
-    \endcode
-
