It seems like the default serial pins (pin 0 and 1) is not enabled on my Arduino 101.
The pins work as they should when declared as output pins and assigned with digitalWrite. However the UART signal on pin 0 and 1 is not initiated by Serial.Begin as it does on my other Arduinos. The TX/RX LED on the board do not blink either.
Do they need to be enabled in some other way? Do my 101 work as it should?
