Interrupt #3

Hi Howard,

What's the difference between what you are doing here and polling? You are going through the loop and constantly checking for the value in the file.

Can this really be considered as interrupt subroutine?

Thanks,

Jack

The read will block until an interrupt occurs. If I was polling, it would return immediately.
