net.wimpi.modbusme.facade.ModbusSerialMaster.writeCoil()
Writes a coil state to the slave. @param unitid the slave unit id. @param ref the offset of the coil to be written. @param state the coil state to be written. @return the state of the coil as returned from the slave. @throws ModbusException if an I/O error, a slave exception ora transaction error occurs.

      //3. Create the master facade
      msm = new ModbusSerialMaster(params);
      msm.connect();


      do {
        if (msm.writeCoil(slaveId, 4, true) == true) {
          System.out.println("Set output 5 to true");
        } else {
          System.err.println("Error setting slave " + slaveId + " output 5");
        }
        BitVector coils = msm.readCoils(slaveId, 0, 8);
