Err, not DJGPP itself, but rather handlers written in C.. DJGPP function
_go32_dpmi_chain_protected_mode_interrupt_vector chains the original
handler automatically. Is there a way to call the original handler only
when I want it to? What I want to do is to handle the keyboard interrupt
(faster for games), but when I want to (ie: with a flag), I'd like the
DOS keyboard handler to handle it instead. Is this possible to do this
in C, or do I have to do it all in assembly?

Read all of the above except for the sources, but it doesn't go in
details.. So I'll go download the sources now :)
