I need to use HW flow control signals, but I've noticed they are not defined in my reference design (TWR-K60D100M).
I've read in the "MQX I/O User Guide" that the using ioctl() commands "IO_IOCTL_SERIAL_SET_HW_SIGNAL" (also similar Clear & Get commands), and the signal defines (IO_SERIAL_CTS, IO_SERIAL_RTS, etc.) - can be used to control the relevant signals.
How do I define & make use if these signals in MQX? How do I define some gpios as signals?
