[Ftdi-usb-sio-devel] About ftdi hardware flow control

[Tao J. <jin...@gm...>]

Hi all 

I have a ft232RL chip that converts USB to uart.  I am trying ti use the hardware flow control. 

I connect the RTS pin on FT232RL to the CTS pin of my serial device, and CTS of FT232RL to RTS of my serial device. 

I use oscilloscope to monitor the signals. I saw that when RTS pin of my device toggles high, FT232RL chip is still sending bits. 

Do I need to do anything in my C program to access the ftdi flow control feature?  Or I just need to hook up all the pins. 

Thanks a lot in advance!
