***Note*** This example uses queues to send each character into an interrupt
service routine and out of an interrupt service routine individually. This
is done to demonstrate queues being used in an interrupt, and to deliberately
load the system to test the FreeRTOS port. It is *NOT* meant to be an
example of an efficient implementation. An efficient implementation should
use the DMA, and only use FreeRTOS API functions when enough has been
received to warrant a task being unblocked to process the data.
