Hi Jay, The quick answer is no. If I remember correctly, I hacked the device tree fragment to set the GPIOs correctly, but found that cape would not work for my application. Using RTS to set the transmit enable is very slow for turn around. I needed to receive right away.
My solution was to use a USB RS-485 that supports HW transmit enable and get rid of the serial cape. Colin..
