i have a [non]protected mode keyboard handler that handles X number of
keys.. if i display it, can someone show me how to change it so it works
under djgpp protected mode?? or am i screwed?

*** start of C file [which worked wonderfully under MS quickC]

#include <graph.h>
#include <conio.h>
#include <dos.h>

//first we'll declare some things we'll need..
#define KEYBOARDINTR 9
#define KEYBOARDPORT 0x60
int exitprog=0;
void (_interrupt _far *BIOSkeyboardhandler)(void);
_interrupt _far keyboardhandler(unsigned int ax, unsigned int bx,
				unsigned int cx, unsigned int dx,
				unsigned int si, unsigned int di,
				unsigned int cflag);

main(void) {

  BIOSkeyboardhandler = _dos_getvect(KEYBOARDINTR);
  _dos_setvect(KEYBOARDINTR, keyboardhandler);

  _clearscreen(_GCLEARSCREEN);
  printf("\n\nHIT ENTER TO STOP\n");
  while (!exitprog)
    ;

  _clearscreen(_GCLEARSCREEN);
  //when the program is finished, we set the old keyboard handler again
  _dos_setvect(KEYBOARDINTR, BIOSkeyboardhandler);
}

_interrupt _far keyboardhandler(unsigned int ax, unsigned int bx,
				unsigned int cx, unsigned int dx,
				unsigned int si, unsigned int di,
				unsigned int cflag){

  unsigned char key, scancode;

  key = inp(KEYBOARDPORT);

  scancode = key & 127;

  printf("%d %d\n",key,scancode);

  if ((scancode == 28) && (key & 128))
    exitprog = 1;

  outp(0x20, 0x20);
}

*** end of c file.. its a horrible program, but it works. is there a
keyboard handler that will do THIS, instead of the sucky 3 button
handler allegro has? don't get me wrong, allegro is awesome, but i'd
rather have a better keyboard handler.. 3 buttons.. what do they think
we are, ANIMALS???
