uart_handshaking

Other Parts Discussed in Thread: EK-TM4C123GXL

Hello,

I am trying to do handshaking (RTS/CTS)  between my microcontroller Tiva C (EK-TM4C123GXL) and an RF module. I am using UART1 for this purpose. After I set the corresponding UART1 pins (RTS/CTS pins), I used UARTFlowControlSet function. Here, I am not sure if I need to do something else. Do I have to look at UART_FLOW_RX flag before  sending data to the Rf module? Or should I use a different function to check whether the RF module can receive my data?

Thanks for help.
