I just want to clarify this so I understand better.  So, even if I 
installed a real mode handler under a DOS DPMI server, it would
never be called and wouldn't be more effecient?

The reason I'm asking is that down the line I also need to write an
interrupt routine for a modem and ethernet cards.

Thanks for responding.
