Subject: RM functions with DJGPP

  I realize that starting with 2.0, DJGPP-compiled programs will operate
only under a DPMI environment, and as such many hardware-interrupt issues
will be more easily resolved.  However, sometimes your need for speed is so
great that you want NO mode-switching when the interrupt occurs.  In these
cases, you need a real-mode handler for when the interrupt occurs in
real-mode.  Will we be able to do this in version 2?  (Even if it has to be
pure assembly I think it would still be very useful.)  
  Also, I understand that under DPMI all interrupts are automagically passed
to the protected-mode hander, regardless of what mode you are currently in
-- will there be a way to bypass this, so an interrupt that occurs in
real-mode will NOT switch to protected-mode and call your PM handler?
  Thanks for any info...
