I would like to automate the termination of the following CODE for SERIAL COMMUNICATION. (termination without readkey())

I'm sort of new to C++. In a current school project, we need to use a sensor to activate an RFID reader. We're using an arduino microcontroller to send serial data when the sensor is activated. I used the following program to read serial data using C++:

#include "stdafx.h"
#include <iostream>
#include "windows.h"

#using <System.dll>
using namespace std;
using namespace System;
using namespace System::IO::Ports;

ref class PortDataReceived
{
public:
    static void Main()
    {
        SerialPort^ mySerialPort = gcnew SerialPort("COM15");

        mySerialPort->BaudRate = 9600;
        mySerialPort->Parity = Parity::None;
        mySerialPort->StopBits = StopBits::One;
        mySerialPort->DataBits = 8;
        mySerialPort->Handshake = Handshake::None;

        mySerialPort->Open();
        mySerialPort->DataReceived += gcnew SerialDataReceivedEventHandler(DataReceivedHandler);
        Console::WriteLine("Press any key to continue...");
        Console::WriteLine();
        Console::ReadKey();
        mySerialPort->Close();
    }

private:
    static void DataReceivedHandler(Object^ sender, SerialDataReceivedEventArgs^ e)
    {
        SerialPort^ sp = (SerialPort^)sender;
        String^ indata = sp->ReadExisting();
        Console::Write("Data Received:");
        Console::Write(indata);
    }
};

int main()
{
    PortDataReceived::Main();
    return 0;
}

I got that from cplusplus.com.

My problem is that I need the program to proceed to the RFID functions after a certain serial data is detected, that's why we used a serial event handler. What I can't figure out is how to terminate the serial event handling mechanism once it detects serial data without having to press any button (ReadKey()). If i remove readkey, the program does not run as I want it to, that is, it does not wait for the serial data anymore. It just closes. What should be done???

I can use a "polling" function to wait for the serial data, but an event handler would be much more efficient than simply looping and waiting for the right data.
