Can anyone answer the following questions:

1) Is it possible to read characters from the serial ports
   before the operating system gets hold of them.
   ie., I want to write a desk accessory which inspects the
   characters coming in off the serial port, before passing
   them onto a terminal emulator.
2) Can a DA `find out' where a terminal emulator has located
   its input buffer.  If I can do this, I may not need to do 1)
   above.
3) Does anyone know where there is technical information on
   writing FKEYs.

   thanks
