Control one light via an existing JavaScript

[clipbrd]

Hello..

Control one light via an existing JavaScript.

If I install something like Homeseer can I control one light with the
JavaScript page already in use??

I don't know if the ports are a concern but, HTTP server is on port 80,
I am thinking of putting Homeseer or similar on port 81..

I am not a HTML/JAVA programmer so any and all info/commands to add to the
JavaScript to make this work would be appreciated..

Homeseer has many more features than I require.
If there is another product to the same but with less features, any info
would be great..

OS on the system in use is Win98SE, running personal web server..
I have an X10 firecracker (CM17a) available to use with setting this up.

Thanks in advance, clipbrd
