It seems that the PL2303 driver doesn't implement TIOCGICOUNT
/usr/src/linux/usb/serial/pl2303.c
static int pl2303_ioctl(struct tty_struct *tty, struct file *file,
                        unsigned int cmd, unsigned long arg)
{
        struct serial_struct ser;
        struct usb_serial_port *port = tty->driver_data;
        dbg("%s (%d) cmd = 0x%04x", __func__, port->number, cmd);

        switch (cmd) {
        case TIOCGSERIAL:
                memset(&ser, 0, sizeof ser);
                ser.type = PORT_16654;
                ser.line = port->serial->minor;
                ser.port = port->number;
                ser.baud_base = 460800;

                if (copy_to_user((void __user *)arg, &ser, sizeof ser))
                        return -EFAULT;

                return 0;

        case TIOCMIWAIT:
                dbg("%s (%d) TIOCMIWAIT", __func__,  port->number);
                return wait_modem_info(port, arg);
        default:
                dbg("%s not supported = 0x%04x", __func__, cmd);
                break;
        }
        return -ENOIOCTLCMD;
}
Perhaps
http://www.mp3car.com/vbulletin/linux/82704-iguidance-2-1-3-wine-7.html has
some hints.
