Re: Multiple UARTs and multiple interrupts - Gary Kato - 18:12 01-07-04

I'm not sure you want to disable interrupts within the UART ISR itself. It has
no bearing on the possible interference between the ISR and your regular code.
You are not allowing for any higher priority interrupts to happen. Granted, the
amount of time that interrupts are off in the ISR is small, but you still might
want to enable higher priority interrupts to occur.
