Hello, we are using the ft232rl breakout board (link below) and would like to send a DTR signal from our serial side to the usb, but the DTR pin on the breakout board seems to be an output only, meaning that DTR can only be sent USB side to serial, not viceversa. How can I send DTR serial side to USB? Do I have to hook up to a different pin such as the DSR to achieve this?
