HardwareSerial Update Confusion

I've searched on how to do this, but found no good, viable, answers. How do you use HardwareSerial in 1.0.3+? I'm not sure what arguments the constructor is wanting me to pass it? The code use to be a simple

HardwareSerial Uart = HardwareSerial();

But now it asks for 13 parameters and I'm not sure what it's asking for. Any guidance is appreciated.

Thanks

What board? The hardware serial is usually pre-constructed for you. You don't need to instantiate it yourself.

Wow, nevermind, the Board got reset to Uno. Thanks guys
