uC/OS-II Event handling on receiving charraters

Hi all.

I am using the MicroC/OS-II environment within my application.

I am just writing a small monitor programm to simply access my hardware via a terminal.

Now I found in the Altera AVALON UART source that event flag handling is already implemented.

I am not realy shure how to use this within my task which receives the input from the uart.

Did someone use it or know how to use it ?

Thanks

Reinhard
