Cannot get change serial to PA_2 and PA_3 on Nucleo F401RE
if I define serial as :-
Serial s(PA_2, PA_3);
If I do the following
s.printf("Hello\n\r");
The serial still comes out on the PC link.
On the board PA_2 and PA_3 are defined as TX and RX.
What am I doing wrong?

PA_2 and PA_3 are the stdio serial pins: they are the ones used for the PC link, so it comes out on both PC and those pins at the same time.
