You cannot communicate with the client devices from the server.

Also, code running in a clients browser cannot talk to hardware connected to them without installing software on them outside of the browser.

No. The server should NEVER contact a client machine for anything.

To do it from a web page on the client browser, you'd have to write a Windows application that gets installed on the client and talks to the device over the serial port. This software would also expose a web server that the javascript in your web page could use to talk to the application and communicate with the device. This web server would be an intermediary between the two.
