Hello, I am trying to wrtie a program in Ubuntu where, throught the console, I can read and write a serial port. So I have started using the qextserialport library. I found code online and tried to emulate it to make a simple test to see if I can get the program to merely connect to the serial port. But alas my program does not seem to be connecting. And I am at a loss for why it won't open the port. Here is my code

Qt Code: 
  1. #include <QtCore/QCoreApplication>
  2. #include <3rdparty/qextserialport/src/qextserialport.h>
  3. #include <iostream>
  4. #include <qiodevice.h>
  5. using namespace std;
  6. int main(int argc, char *argv[])
  7. {
  8.     QCoreApplication a(argc, argv);
  9.     const char data[]= "e";
  10.     QextSerialPort * port = new QextSerialPort("/dev/ttyUSB0");
  11.        port->setBaudRate(BAUD115200);
  12.        port->setFlowControl(FLOW_OFF);
  13.        port->setParity(PAR_NONE);
  14.        port->setDataBits(DATA_8);
  15.        port->setStopBits(STOP_1);
  16.        port->setTimeout(10);
  17.        bool res = false;
  18.        res = port->open(QIODevice::ReadWrite | QIODevice::Unbuffered);
  19.  
  20.        if(res)
  21.           {
  22.               cout << "Opened" << endl;
  23.               char i = port->write(data);
  24.           }
  25.           else
  26.           {
  27.               cout << "Failed to connect" << endl;
  28.           }
  29.           return a.exec();
  30.        }
To copy to clipboard, switch view to plain text mode 
The console that is opened always displays "Failed to connect"
Can anyone see any very obvious erros?

Thanks
