[go-nuts] Golang serial port get CTS and DSR values

[hchameera]

Hi,

I just want to know, how to get CTS and DSR values in windows environment. 
i have tried below way, but it did not work for me; Can u please look into 
this?


func (p *Port) getCtrlSignal(sigmask uint) (bool, error) {

    state := uint(0)
    _, _, errno := syscall.Syscall(
    syscall.SYS_IOCTL,
    p.file.Fd(),
    uintptr(syscall.TIOCMGET),
    uintptr(unsafe.Pointer(&state)))
    if errno != 0 {
        return false, fmt.Errorf("ioctl TIOCMGET %d", errno)
    }
    return ((state & sigmask) != 0), nil
}



Thank You!!!
