No there is not such an animal. The lack of it is due to the fact
that programs created by gcc run in 386 protected mode, and interrupts
may come in either when in protected mode or real mode. See the file
AEASY101.ZIP, part of the 1.09 distrib, for an example of how to handle
interrupts using a TSR.

If there's an FAQ for this mailing list, could the holder thereof please
explain this topic in its next incarnation (or mail me, and I'll prepare
and explanation for inclusion)? Thanks.
