> Please read the '[PATCH/RFC] 8250: Auto RS485 direction control' thread for background information. In a nutshell we need more than just CTS/RTS and DTR/DSR, and we don't have enough c_cflags bits. We will probably have to create a new ioctl.

Maybe - fortunately the kernel and user termios structure are now
independent so we can extend ktermios easily enough.
