	// are always faithful - suppose your game only opened port 2 for some reason,
	// then a disconnect value would look like 0x0002D100.
	//
	// MTAPMAN however does not check the bit set by 0x00020000. It only checks the bit
	// set by 0x00010000. So even if port 2 is being addressed, cmd stat should be 0x0001D100
	// (or 0x0001D200 if there are both ports being accessed in that packet).
