> Hi,

> I am implementing a 2nd uart driver in eCos on the

> 1. I plan to use a different uart base address and a
> different interrupt number for the second uart. Can
> I
> share the same ISR routine for both uarts?
>
> 2. In which situation should I use polling and
> interrupt method? I plan to use the interrupt

> 3. Where can I get sample implementation for 2 uart
> driver?

> Thanks.
