Hi, sorry for my newbie question, What is the status of the serial port driver? I've written some code to use serial ports for the generic kernel linux, And now I want to write something similar for the real time kernel, do I have to use some specific library, flags or something or is it just the same settings? I'm asking because now I need to take into account the serial access in the scheduler to ensure a real time behavior . Any help, advice, hint or tips would be appreciated.
