I know how hardware flow control works. I envision using CTS/RTS in my app for flow control. However I am confused
on just what exactly the flow control setting does as far as the control is concerned. Does it implement flow
control for you behind the scene (looking at the receive buffer)? Or do you have to implement it yourself by
controlling the RTS line when inbuffercount reaches inbuffersize? If you have to implement the flow control
yourself that is why I question what the setting does.
