Signal handling for 3 serial interrupt.

Hi all,

I have 3 different devices Dev1, Dev2 & Dev3 connected to UART 1, UART 2 & UART 3 respectively. I am using these 3 devices alternatively.
I want to write signal handler for these 3 devices interrupts. I am able to handle one signal handler at a time.

But problem is that when I have tried to write signal handler for other (means two signal handler at a time for SIGIO signal), my programs does not work.

Can anybody tell me how to solve this problem?

Please help me.
