Subject:	Interrupt Descriptor Table and hardware interrupts.

Hi,

I'm implementing an interrupt driven data acquisition system using an
8255 based interface card.  I want to write an interrupt handler which
will be installed when my program starts up and removed on exit.
In the libraries for djgpp I can't find an equivalent to the setvect()
function available elsewhere.  How can I place an entry in the IDT under
djgpp?  Any  advice on hardware interrupt handlers under djgpp and in
protected mode would be appreciated.
