[En-Nut-Discussion] Any way to get an interupt (NutEventWait) when a UART RX buffer has something in it?

I've got a UART (ARM7) that may get unexpected asynchronous input. I have
multiple threads running and if the UART gets something, I like to switch
that thread and service the UART (read the buffer).
Is there a something like an internal interrupt that I can use or some how
Right now I'm polling and checking the buffer. It works but I don't like
it and I'm afraid it's slow and I might be missing something.
THREAD( AppCommandServer, arg)
parm = 1; //textmode
_ioctl(_fileno(cons), UART_SETCOOKEDMODE, &parm);
_ioctl(_fileno(cons), UART_GETSTATUS, &parm);
if (parm & UART_RXBUFFEREMPTY) //if empty
// printf("RX: Buffer Empty\n");
} //end of for(;;)
