This module adds interrupt driven receive on UART 0. Using semaphores, a thread calling read(...) when no data is available will block in an RTOS expected manner until data arrives. This allows for a background thread running a serial terminal in your program for debugging and state inspection consuming no CPU cycles at all. Not using this module will make that thread while(1) until data arrives. No code changes are needed for adding this module, all you need to do is to add it to EXTRA_COMPONENTS and add the directive configUSE_COUNTING_SEMAPHORES from FreeRTOSConfig.h in examples/terminal to your project.
