I've long used this little bit of code to determine if a
	particular printer port is available or not.  It works 
	fine on my old 486, returning false and true when it
	should.  But alas, I upgraded... and am now running a P75
	with a PCI Board, and this code no longer works.  subfunction	
	00h prints no problem but when a different port is selected,
	LPT2, etc, it hangs until my printer is On-line, and then it
	attempts to print(for an average 1 page document this takes
	about 2 minuutes of my computer sitting there doing nothing).

	I took a look at a few PCI docs, including Ralf Browns stuff,
	but couldn't find any applicable information, does anyone out 
	there know any more about this ??



  __dpmi_regs r;
  r.h.ah = 2;
  r.h.dh = port;
  __dpmi_int(0X17, &r);

  if( (r.h.ah&0X08) != 0 ) return TRUE;
  return FALSE;
