I solved the problem :smiley: i dont know why but the computer recognized what i was tried to type when i used this simple code below
with this schematic tutorial RS232 Communication - The Level Conversion - eXtreme Electronics

 #include <SoftwareSerial.h>
SoftwareSerial portOne(6, 7);

void setup()
{

  Serial.begin(9600);
    portOne.begin(9600);
}



  
void loop()
{


  portOne.write('x');
  float x = portOne.read();
  delay(100);
  portOne.write('y');
  float y = portOne.read();
  delay(100);

  Serial.print(x);
  Serial.println(y);  

}
