Clearing the terminal screen?

I have found that ASCII 12 make a Form feed, that is a new page. here is a wikipedia definition

"Form feed is a page-breaking ASCII control character. It forces the printer to eject the current page and to continue printing at the top of another"

The code is

Serial.write(12);

Arduino Terminate doesn't support the character but Putty a light open source telnet client can do it

An Example of the code

void setup() {
  Serial.begin(9600);//Initializase the serial transmiter speed

}

void loop() {
    //Code tested with Putty terminal

    Serial.write(12);//ASCII for a Form feed
    Serial.println("This is the title of a new page");// your code

    delay(500);//delay for visual
    }

There is no way to clear the screen but, a really easy way to fake it can be printing as much Serial.println(); as you need to keep all the old data out of the screen.

The Arduino serial monitor isn't a regular terminal so its not possible to clear the screen using standard terminal commands. I suggest using an actual terminal emulator, like Putty.

The command for clearing a terminal screen is ESC[2J

To accomplish in Arduino code:

  Serial.write(27);       // ESC command
  Serial.print("[2J");    // clear screen command
  Serial.write(27);
  Serial.print("[H");     // cursor to home command
