Chris, for DOS, try:
class KeyState {
  private:
     const char far *ks;   // Pointer to BIOS keyboard flag
  public:
     // Use a constructor to initialize the pointer
     KeyState() { ks = (char far *) 0x00400017L; }
     // If your compiler doesn't support bool's use int
     bool CapsState(void) const   { return (bool) (*ks & 0x40); }
     bool NumState(void) const    { return (bool) (*ks & 0x20); }
     bool ScrollState(void) const { return (bool) (*ks & 0x10); }
};
// Test with this...
#include 
int main(void)
{
  KeyState k;
  if(k.CapsState())
    cout << "Caps State is on";
  else
    cout << "Caps State is off";
  cout << endl;
  if(k.NumState())
    cout << "Num State is on";
  else
    cout << "Num State is off";
  cout << endl;
  if(k.ScrollState())
    cout << "Scroll State is on";
  else
    cout << "Scroll State is off";
  cout << endl;
  return 0;
}
