I still have PISD (Post Interrupt Service Disorder) from writing bimodal interrupt handling. One of my MS-DOS projects ran under the DOS4GW DOS extender (same as DOOM), which let the body of the application run in protected mode. The extender would automatically switch from protected mode to real mode to handle an interrupt, and then back again. Unfortunately that was slow, so you could be bimodal instead. You installed both a real-mode and a protected mode interrupt service, and could therefore omit the expensive mode switched. Sharing data between the two was left up to the developer. My solution was to create the data areas in the real-mode code, and pass the address to them in the command line when the real-mode started up the protected mode code. I was handling three RS-232 ports running at 56K, along with three parallel ports outputting 100KB per second, on a 16 MHz 386SX processor.

The really neat trick was using the same C source code for both the real and protected mode interrupt services.

Were you affected by the geomagnetic storms this past weekend?
Communication disruptions, electrified pipes, random unexplained blue-screens in Windows - the list of effects is terrifying.
