It's at the same level as SerialByteComm; so transmits are split-phase  
operations, receives are events.

It's probably more helpful to think of the interface in terms of its  
effects on interface state machines, rather than an implementation.  
E.g., I would assume that disableRx() would prevent future get()  
events, while disableTx() would cause put() calls to return EOFF or  
some other error code.
