Parameters:
[in] uart UART number (0..2)
[in] *buffer pointer to buffer to be sent
[in] len number of bytes to be sent
Returns:
0 if no error
-1 if UART not available
-2 if buffer full or cannot get all requested bytes (retry)
-3 if UART not supported by MIOS32_UART_TxBufferPut Routine
Note:
Applications shouldn't call these functions directly, instead please use MIOS32_COM or MIOS32_MIDI layer functions
