what you need is called a "system call". In real mode, that's as easy as writing the code:segment values of your system call in the "Interrupt Vector Table" and terminating your handler with a "iret" instruction.

There are certainly profusion of such tutorials; google for "TSR" programs (Terminate and Stay Resident) -- if you got how they work, you should be ready to face kernel system calls.
