[ECOS] Serial interrupts on the AEB

I have had a go at this. I have set the  Interrupt Enable Register for 
UART0, UART1 and UART2. I'm not entirely sure which one is the serial line. 
This has no effect though, my ISR function is still not called when data 
arrives on the serial line.

I thought stuff like this would be abstracted away by ecos. Isn't that the 
point of using an OS, to protect you from having to mess with the hardware 
in such a way? I thought there would be an ecos function like 
make_uart_interrupts_work(). Or is it because this is so hardware specific 
that it is still left up to you to do manually.

Gary Thomas mentioned using the serial driver to do all this. Can anyone 
point me at some example code to get me started?
