One way to do this:

- use the bios directly to get all keystrokes; there is a function in 
  TurboPascal (probably called BiosKey or something) to do this. That
  will let you get ^C, ^S, ^P, ^Q, and lots of other goodies that
  would otherwise have special meaning.

- install your own ctrl-break handler. For this I refer you to any 
  good book on programming with interrupts, or the interrupt list.
  Basically you need to use the DOS getvector function to find out
  where ctrl-break's are going, then DOS setvector to redirect them
  to one of your functions, then finally setvector when your program
  exits to restore the original Ctrl-Break handler. 

Perhaps there is some built in Turbo Pascal-specific way to do this?
