Serial communication from JavaScript?

Question

Is it possible to communicate over a machine\'s serial port through JavaScript?

I have to write a short program that sends data to a microcontroller over the serial

Answer 1

Yes, it's possible using an ActiveX(I did it). You can make an activeX and use JavaScript to invoke it. If you prefer, you can make a .net dll and register it using regasm. Take a look at this link

You also can write an activeX using VB6 and register it. Both works fine. Ps.: if you are using ActiveX, the JavaScript code will run just on IE.
