Phar Lap provides "Shadow Interrupt Vectors" that routes both real-mode and protected mode interrupts to your handler. This made life easy. I have the queue driven RX/TX handler working using shadow vector table. For the embedded application, the software will be in protected mode just after boot-up.

If you are interested in the code, let me know. Arguments are passed on the stack, by reference and string descriptor. Common blocks hold the structures.
