Hello, At least in the am3505/3517 CPUs, the built-in uarts only expose the RX/TX/RTS/CTS signals. Other signals such as DTR/DSR/RI and DCD, while very useful when controlling a modem, are not available. My design has the above mentioned extra signals wired to GPIOs. Controlling them through sysfs is possible, but not convenient as I needed the standard serial port ioctls to work. There did not seem to be anything in place to do this so I've come up with the following two patches which I am using for now. What do you think? Is there a simpler, more obvious solution? Did anyone attempt doing something to attain a similar goal in the past?
