Original description

What change would you like to see?

I would like this sketch:

void setup()
{
  Serial.begin(57600);
  Serial.print("Hi There!");
  Serial.print("\r...");
  Serial.print("\nThere!");
}

to generate this output:

...There!
   There!

rather than what we get today:

Hi There!
...
There!

That is CR should move to beginning of line and LF should advance to next line.

Why?

This allows for more flexible debug output. A trace value can be rewritten to the same line (Serial.print("\rValue=")) rather than print on a separate line.

Would this cause any incompatibilities with previous versions? If so, how
can these be mitigated?
Not likely. Serial.println uses the CR/LF pair for line endings and so would produce the same output as today. This is also inline with how CR/LF is defined and how most serial terminal emulators work.

Closing as wontfix. Use an external program like putty
