I am trying to verify the Arduino code in ADS1198 and Arduino Due. It comes the error show 'Serial1' does not name a type' even I defined two serial port in the beginning(where I gave the comments now). How to deal with this error 'Serial1' does not name a type'. how can I define these two port on ArduinoDue so that complieling successfully.

#include <ads1298.h>
#include <Base64.h>

// Minimal sketch for connection to ADS129n family. Load this script and open Tools/SerialMonitor. 
// You should see text like this
// Device Type (ID Control Register): 62 Channels: 8
// If you see "Channels: 0" then check your wiring

#include "ads1298.h"
#include "adsCMD.h"
#include <Base64.h>


#include <SPI.h> // include the SPI library:
int gMaxChan = 0; //maximum number of channels supported by ads129n = 4,6,8
int gIDval = 0; //Device ID : lower 5 bits of ID Control Register

int activeSerialPort = 0; //data will be sent to serial port that last sent commands. E.G. bluetooth or USB port
const int kPIN_LED = 13; //pin with in-built light - typically 13, 11 for Teensy 2.0.

void detectActiveChannels()

Serial1.begin(115200) and Serial.begin(115200) need to be placed in a function. Put them in setup().
