In the PC world, yes, there is little need for RS232. In the embedded world,
there are TONS of little devices that use async serial to communicate. For
example, look at the number of things available for connection to the BASIC
STAMP.

And if you want to talk to, or listen in on, one of those devices with your
PC during development, you may find you need a little gizmo to convert TTL
to RS232 so your USB/RS232 adapter will work.

Now, there are a billion designs for such a thing, but rather than take the
time, you can just keep one of these on hand:

And I was thinking about what could possible make it more useful to people.

Just idle thought.
