Javascript and the Serial Port

[steven01]

Anyone know how I can send serial commands to the COM port of the users machine using Javascript?

I'm pretty sure you can't. It would be a security risk for a language like JS to have such capabilities.

Even if I could say launch an external application via Javascript to accomplish this?

I would be completely satisfied even if I had to custom configure each users PC to allow this as this web site will be limited to a very small number of specialised clients.

There seems to be a way using activeX. Check out
