Baud can range from 7813 - 2400000 baud, but values less than 2000000 (2 Mbaud) are recommended.
Implemented in HardwareUart.

- Returns
- The bytes received
As soon as the UART is enabled, any received byte will be added to a 32-byte buffer. Calling this Receive() function does two things:
- sends the current contents of this buffer to this function.
- reset the pointer in the buffer to the 0th element, effectively resetting it. If the buffer fills before the Receive() function is called, the existing buffer will be reset — discarding all data in the buffer. Consequently, it's important to call the Receive() function frequently when expecting data.
Owing to how it is implemented, you can clear the buffer at any point by calling Receive(). It's common to empty the buffer before requesting data from the device attached to the UART; this way, you do not have to worry about existing gibberish data that might have been inadvertently received.
Implemented in HardwareUart.
