Greetings folks.
  I am trying to write a interrupt handler for the keyboard.  I want to make
the function keys on the extended keyboard do something.  Here's the problem
in a nutshell.  I install my handler with SetVector and it returns fine.  The
problem is that after its installed and the interrupts are enabled, IntSource,
I don't get an interrupt with every key press.  I put a brk instruction as the
first line of code, and it doesn't break until several keys have been pressed,
and then doesn't break again for several more chars.  Anybody got any ideas?
Anybody at all?  Any and all help greatly appreciated.

Thanks,
Roy
