UART Read Non Blocking STM32F217?

I am working with the UART_Hyperterminal_IT example in STM32Cube_FW_F2_V1.7.0.  My micro is STM32F217.


My calls to HAL_UART_Receive_IT() are blocking.  That is probably the expected behavior, but I would prefer to:

1. have the call return immediately with some bad status if no data is available


2. use some other call that checks data available in the UART before I call Read.


Is that possible?
