Hi,

I've a user here who wants to implement a "Terminate and Stay Resident"
type application on a Unix box.  Here's the situation:

  1.  He has an "off-the-shelf" application that he's using.  No
      source code available.  If his "chosen key sequence isn't
      entered - then the input gets passed to the application and
      the TSR continues to listen.

  2.  He wants to develop an application to run in the background,
      capture his input - and perform "something" if a certain key
      combination is received.
  
My dilema is, I'm not sure which application will be controlling the
I/O.  If he starts his "TSR" and shoves it in the background - will
it still have access to the I/O coming from the keyboard once he 
starts the application he wants to use?

I'm lost.
