Arduino ethernet BOARD example

Nothing happens automatically. You must have some code that makes this happen. Where is that code?

while(client.connected() && !client.available()) delay(1); //waits for data
  while (client.connected() || client.available()) { //connected or data available
    char c = client.read(); //gets byte from ethernet buffer
    Serial.print(c); //prints byte to serial monitor 
}

Perhaps you noticed that blank line

yes i did

but how do i delete the first lines?
or how is it called doing this?
then i can read/search about this...
