[net.micro.mac] Serial Driver Question

jules@neumann.une.oz (Julian Creedy) (10/12/86)

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

   don't quote me on anything, least of all this topic but...

  I think fkey's are just 68000 instructions, hexed of course, stuffed into
an fkey resource. (that's TYPE = FKEY).
