Is there any way to make a text area and not to show (or permit to write) the scroll bar,

<textarea style="overflow:hidden" rows="3" name="S1" cols="20" ></textarea>

it hides the scroll bar but don´t limit the entry only to 3 rows, and that's what i want

You have to use javascript to do that..
Here is the function i used to limit the total lenght of the inserted message:
You can change the stri.length check with a rows check.. probably counting the number of '\n' in the message. Quite trivial if you check char by char.

function maxLength(tbox)
{
  var stri = tbox.value;
  if (stri.length > 255) {
    alert('Please don\'t type more than 255 characters');
    tbox.value = stri.substring(0,255);
    return false;
  }
  else
    return true;
}
