I'm using the below code to check the console input buffer which would be STDIN for an `ESC` key press.


Even when it seems there nothing in '0', read returns 1 and prints what it reads.  Which is nothing.  I intend to use this to see if a user has

presed the ESC key on bootup.  This program will be called fomr /etc/rc.d/sysinit but before the loading of the serail driver.  When the serial driver loads, it will flush STDIN.  Am I doing what I want in the proper manner?

Thanks,
Chris
