I first tried this for Amiga Empire on my A1000. The light on my modem did
NOT go off. I had to go directly to the hardware and toggle the bit - that
DID work. The problem went away when I got an A2000. On other machines, the
open/close combo did work. I don't at all understand how this was happening,
but it was quite repeatable. Also, a friend's A1000 has the same problem.
