For auto configuration of attached modules, ie ESP, GPS etc etc... I'm looking for changing the Baud at runtime to see which one is correct.
Can this be done?

Serial.begin(9600);
while(Serial.available()) Serial.read();
// Do some ping-pong and check if something is coming along.
// If not change the Baud and try again
Serial.flush();
Serial.begin(115200);
while(Serial.available()) Serial.read();
