It may not be exactly what you decribe but have a look at
<http://www.easyvitools.com/index.html>
he has a com port to browser interface  & mini web server.
Also tools for building a windows control panel that drives devices by
serial ports or ethernet etc.

You just use a BASIC style language to describe what you want. The
downside is that it is a bit slow & there is minimal error checking so
incorrect syntax just results in things not working,
If you can find a copy of the earlier demo version ezcom2web server
program it is less restricted than the later one.
