UART acess


Hi, everybody
I am new to openAT. I am little aware of RTOS concept.Now i have an assignment on OpenAT. I need to give input from system serial port and i need to process that data and i need to send sms. .But now i am trying to do UART interface. The example app given [UART acess] i couldn’t understand that Generic event handler table and event services. Any one please guide me. How dynamic event works and that event mask, inner event mask…Please

Thanks and best regards
