this is a program code for example:

#include <Wire.h>
#include <ITDB02_Graph16.h>
extern uint8_t SmallFont[];
ITDB02 myGLCD(A1,A2,A0,A4,A5,2); //

void setup()
{
Serial.begin(9600);
myGLCD.InitLCD();
myGLCD.setFont(SmallFont);
}

void loop()
{
int buf[238];
int x, x2;
int y, y2;
int r;

myGLCD.clrScr();

myGLCD.setColor(255, 0, 0);
myGLCD.fillRect(0, 0, 239, 13);
myGLCD.setColor(64, 64, 64);
myGLCD.fillRect(0, 306, 239, 319);
myGLCD.setColor(255, 255, 255);
myGLCD.setBackColor(255, 0, 0);
myGLCD.print("prove", CENTER, 1);
Serial.print("TEST PC");

When I open the hyper terminal screen turns off. I need not turn off and I want to communicate with a PC to modify or query data during program execution.
