UART Serial Communication

Hi, I am trying to implement a code that is able to receive input from a serial communication. I believe that it is possible to do this using fstream, but so far I have been unsuccessful. The code below should echo everything received on screen:

Code:

---

#include <iostream>
#include <fstream>


int main(int argc, const char * argv[])
{


    std::string msg = "";

    std::cout << "Hello, World!\n";
    std::fstream file("/dev/tty.usbserial-A800F2GZ");
    if (file.good())
    {
        while(1){
        file >> msg;
        std::cout << "Response: " << msg << std::endl;

        }
    }

    return 0;

}

---

Any ideas?

Currently using: Mac OS X 10.8.5, Xcode 5

Define "unsuccessful"; compile issue? runtime fault? just no output? something else? If nothing else, you should have an else for your if that tells you why file is not good().

It also won't work if the sender isn't sending using the default baud rate and parity settings for your dev/tty
