Getting data from two serial monitor

Hello,

I have connected a GSM modem to pin no 2,3 of the mega and trying to read data from modem and display it on serial monitor, for testing purpose i have made a call through modem and it works fine but i am unable to read data from it . I have used some code from the link Serial Input Basics - Programming Questions - Arduino Forum
which gives details of reading a string from serial monitor. here is my code

#include<SoftwareSerial.h>

const byte rxPin = 2;
const byte txPin = 3;

SoftwareSerial mySerial(rxPin,txPin);

void initCall();

const byte numChars = 32;
char receivedChars[numChars];
boolean newData = false;

void setup() {
  delay(20000);
  pinMode(rxPin, INPUT);
  pinMode(txPin, OUTPUT);
Serial.begin(9600);
mySerial.begin(9600);
delay(500);

initCall();
 Serial.println("Serial call");
delay(20000);
mySerial.println("ATD>SM1"); 
// this works fine and calls number which is located in sim
delay(45000);
Serial.println("Call has been made");
}

void loop() {

}


void initCall()
{
 
  mySerial.println("ATZ");
 recvWithEndMarker();
 showNewData(); // expected result is OK
  delay(2000);

 
  mySerial.println("ATE0");
 recvWithEndMarker();
 showNewData(); // expected result is OK
  delay(2000);

  mySerial.println("AT+CNMI=1,0,0,0,0");
 recvWithEndMarker();
 showNewData(); // expected result is OK
  delay(2000);

  mySerial.println("AT+CRC=1");
 recvWithEndMarker();
 showNewData();// expected result is OK
  delay(2000);

  mySerial.println("AT+CMGF=1");
 recvWithEndMarker();
 showNewData();// expected result is OK
  delay(2000);
  }

void recvWithEndMarker() {
 static byte ndx = 0;
 char endMarker = '\n';
 char rc;
 
 // if (Serial.available() > 0) {
           while (mySerial.available() > 0 && newData == false) {
 rc = mySerial.read();

 if (rc != endMarker) {
 receivedChars[ndx] = rc;
 ndx++;
 if (ndx >= numChars) {
 ndx = numChars - 1;
 }
 }
 else {
 receivedChars[ndx] = '\0'; // terminate the string
 ndx = 0;
 newData = true;
 }
 }
}

void showNewData() {
 if (newData == true) {
 Serial.print("This just in ... ");
 Serial.println(receivedChars);
 newData = false;
 }
}

Ditch the SoftwareSerial, you have a Mega! It has 4 sets of hardware serial!

If you ARE hung up on using SoftwareSerial, RTFM, and see which pins you can actually use on the Mega.

Actually i don't know how the hardware serial works but i shall learn now.

I tried with hardware serial and it worked , thanks for the suggestions.
