Afaik, you'd haveto walk the device driver chain and query each handler
with int21h function 44h, subfunctions 00h-0Fh. Also check the printer
drivers at int21h, 5Eh and the redirected drivers at int21h, 5Fh subfunction
02h. Country code page info is at int21h function 65h and 66h.

All the int 10h ints are used for bios calls. Also check out int 15h, int 16h,
int 17h, int 33h. Int 67h may be useful too, if you have an EMM handler
installed and need EMM info.

Someone wrote Eu code in the archives that uses dos interrupts, i'm sure
you could use that as a framework to build on.
