Javascript interface with RS-232 serial port

Question

I am currently working on a project that includes a 4-port A / V switch. This switch can be controlled via RS-232.

The computer that will interact with the switch starts Vista. I would like to create a sidebar gadget with 4 buttons - 1 for each switch port. When the user clicks the button, he switches to this port.

I have worked a little with the search engine and it seems that there is no good way to interact between javascript and rs-232.

Does anyone have any suggestions for me?

Thanks!

AFAIK, the Gadget Vista runtime supports the use of signed ActiveX controls. You can also use Java. You can create an ActiveX wrapper for .Net that has sufficient support for serial devices. For the most part, ActiveX + Serial Communications is limited to commercial controls.
