Most drivers waits for hardware to detect carrier and for closed callout.

Thanx for your respond,

I did not implement this function in my tty driver.

Does it help to work my driver with cat Linux operation?
(e.g. cat < ttyS10)

Help in which way? If you haven't implemented it, it'll behave like there was 
O_NONBLOCK passed to open() call or TIOCSSOFTCAR ioctl with nonzero param was 
invoked.
