Note that this flag does not directly control RTS, but rather it
instructs the kernel whether RTS/CTS signalling should be used for
flow control or not.
As David noticed, there is no API for directly controlling RTS in
Linux, it can only be done by the serial driver itself or a line
discipline driver.
