I've had a look at the links you gave, and it made a lot of sense to me
because I've been worrying about collisions in usage of the SIO. I'm
pretty sure I can make good use of your module.
One thing that I must mention though, is that in order to discover the
actual SIO address, I have had to access other regions, and these are
not always the same; the actual address depends on a) the bootloader,
and b) how pins are strapped.
The long and short of this is that I will need to make use of your
locking mechanism on all of the addresses, not just on the SIO address.
Looking at your code, that doesn't seem to be a problem though. I only
need to lock 3 or 4 addresses briefly.
If my explanation is too vague, I'll send you my module, and you can
have a look to see how I do it, but it's not very readable unless you
have the sc1100 data-sheet close at hand. Just shout if you want to see

Thanks. But you could also hang on until I submit a more final version,
because I've drastically improved the discovery of the SIO address now,
plus got interrupt-driven mode working nicely.
