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.
