The following code never ends (it loops inside the " Serial3.readString() " when and only when the rx line is always HIGH ('1' logic):
String rxReply;
Serial3.begin(1200, SERIAL_8N1);
while(!Serial3);
Serial3.setTimeout(200); // 200 is just an example and if you print Serial3.getTimeout() you'll get the right result
rxReply = Serial3.readString();
// When the rx line stays high ('1' logic) the execution never arrives here, as if the 200ms time-out never expired
// Conversely the code is properly executed when the rx line is low ('0' logic)
Serial.print(rxReply);
Could you take a look at this anomalous behaviour?
