+Alternatively, ``UartC`` may provide the UartStream multi-byte level
+interface. See the Low-Level I/O TEP [TEP117_] for details.

+Additionally, UartC provides a split-phase interface to signal when
+the UART is idle. There are situations (such as when powering down the
+usart, when switching from TX to RX on a radio with a UART data line,
+etc.) when we need explicit information that the data sent over the
+UART has actually been transmitted in full. The problem is that on
+MCUs that double-buffer UART communication (such as the msp430), a
+putDone event signifies that the UART is ready to accept another byte,
+but NOT that the UART is idle.

 It also provides interfaces for configuring the serial port. *NOTE:
 These are not codified yet, and so working out the UART HIL seems like
 a good idea.*
