Knock yourself out!

I doubt anybody would be interested in using a graphical interface
communicating over serial though.

If you have a board that's worth putting graphics processing on, you can
probably run Linux (and thus X applications on your host computer's

The only half-serious use of graphics on an eCos target, driven via
*serial*, would be by employing a web server. Then the host can access
the target's "GUI" by a simple browser. HTML transport is cheap compared
to a bitmapped graphics GUI.  And people use HTML via serial every

So in summary: what you are after is a web server, tied in with your
application. There's already a web server available for eCos (I don't
