* Function description
* Reads characters from SEGGER real-time-terminal control block
* which have been previously stored by the host.
* Do not lock against interrupts and multiple access.
*
* Parameters
* BufferIndex Index of Down-buffer to be used (e.g. 0 for "Terminal").
* pBuffer Pointer to buffer provided by target application, to copy characters from RTT-down-buffer to.
* BufferSize Size of the target application buffer.
*
* Return value
* Number of bytes that have been read.
