Serial port freezes

/*

Interface to Orbiter Flightdeck

int analog = 0;
char pitch[11];
void setup()
{
  Serial.begin(115200); 
}

void loop()
{
  analog = analogRead(0);
  sprintf(pitch, "<129 %4d>",analog);
  Serial.print(pitch);
  for(int i = 0; i<100; i++)
  {
    sprintf(pitch,"<%3d %4d>",i,i*10);
    Serial.print(pitch);
  }
}

I doubt that this code never "freezed." It fills the TX buffer quite quickly.
