sets the length of the data appended after the protocol header . note that this library , a bit in contrast to the specification , counts the unit identifier and the function code to the header , because it is part of each and every message . thus this message will append two 2 to the passed in integer value . concode_field_sep boolean m_Headless concode_elem_sep int m_ProtocolID concode_elem_sep int m_TransactionID concode_elem_sep int m_DataLength concode_elem_sep int m_UnitID concode_elem_sep int m_FunctionCode concode_field_sep boolean isHeadless concode_elem_sep void readData concode_elem_sep void readFrom concode_elem_sep String getHexMessage concode_elem_sep void setHeadless concode_elem_sep void setHeadless concode_elem_sep int getUnitID concode_elem_sep int getProtocolID concode_elem_sep void writeData concode_elem_sep int getFunctionCode concode_elem_sep int getDataLength concode_elem_sep void writeTo concode_elem_sep void setProtocolID concode_elem_sep void setUnitID concode_elem_sep int getTransactionID concode_elem_sep void setTransactionID concode_elem_sep void setFunctionCode concode_elem_sep int getOutputLength
