hi somebody knows how to set DTR signal to high in MQX ? (supply the DTR pin with a constant positive voltage)

I am using the TWR MCF51CN128 with MQX 3.2

i found in the MQX I/O Users guide that we can call _io_ioctl( ) and pass the hw signal commands in order to assert the DTR signal so i tried the following

_io_ioctl( IO_IOCTL_SERIAL_SET_HW_SIGNAL |  IO_SERIAL_DTR);

 

but it didnt work

so please if sombody knows how set DTR signal to high in this way or another it will be very helpful

thanks
