Yes. Sorry to be blunt!

It's a complex isssue. For a fuller treatment, read:

http://www.abwillms.demon.co.uk/prog/djints.txt

A tutorial on DJGPP interrupt handling (oddly enough).

If you install Bill's GCC patch mentioned in there, you can use my
very own (shucks) libhw at http://www.abwillms.demon.co.uk/libhw.zip
to make most of it easier, and also use prewritten handlers for things
like... keyboard interrupts! If you want to do something special, you
could at least use that code as a basis for your own handler.

No such thing as a rudimentary interrupt handler in DJGPP :-)
