Hello,
I am using the STM32f103c series controller with GSM module. Sometimes Serial buffer of GSM is getting full and the communication is not happening as expected. During my search, I came across Hardware Flow control using RTS/CTS. As stm has dedicated H/W flow control pins [For UART 2 PA0:- CTS2 & PA1:-RTS2] is there any option available in board files to enable hardware flow control?
if yes please let me know how to enable it
if not then it would be really helpful if you can integrate this in next version.

Thanks
