Chrome 中的串口通信

Question

I have a legacy application which is making use of ActiveX control for serial communication. This is rightly communicating in IE.

Since ActiveX is IE specific technology obviously it will not run in Chrome or other browser

So I don't want to disturb the IE functionality and thought of introducing browser specific function as below.

$(document).ready(function(e){

 var isIEBrowserFlag = true;
 if(isIEBrowserFlag)
 {
  var obj = new ActiveXObject("MSCommLib.MSComm");
  obj.CommPort = commPort;
  obj.RThreshold = thresHold;
  obj.Settings = settings;
  obj.PortOpen = true;
  obj.DTREnable = true;
  obj.Output = "test";
 obj.PortOpen = false;

//other stuff
 }
 else
 {
    //chrome
 }
 //sendBagToPrinter(obj);
});

On googling I came to know about jQuery.parseXML() but how do I implement the same functionality as of IE in Chrome using $.parseXML()

Similar other plugins such as juart were tried, but not fitting my requirement.

chrome.serial API provides access to client serial ports, but from a Chrome App. My suggestion, for future support, use/write some kind of server for serial device and connect from browser to server via a json type communication. See https://github.com/johnlauer/serial-port-json-server
