linux - Can we detect UART overrun error from user land?

Question

I'm using Linux-2.6.35　released from freescale git.

I want to detect UART overrun error from user land. Now I receive UART RX data using opening sysfs file and using read(2) API. But it seeems to me that read(2) cannot return error(-1) even though overrun has occured.

Is there any measure to detect UART overrun error from user land?

(When I read "/proc/tty/driver/auart", I can aware wether overrun has occured or not. But when overrun has occured, I want to tell it to application without polling such files or filedescriptor.)
