Under Windows, there may be access to a scripting object that can access
the serial ports. I would ask in microsoft.publi c.scripting.wsh
If this MUST be done in a web browser, the best option is to run a
separate program to read in the serial data and write it to a text file.
The web browser can use HttpXMLRequest to re-read the file as needed.
Might I ask why you need to do this?

binding for (the) ECMAScript implementation( s).
And there is no reason why you could not use that "scripting object"Under Windows, there may be access to a scripting object that can access
the serial ports. I would ask in microsoft.publi c.scripting.wsh
(actually an ActiveX/COM object) from within MSHTML, may it be Internet
Explorer or an HTA. There is also XUL to consider for Gecko-based UAs.
