title: how to get the data from serial port (RS-232) on client side
body: <p>My project i'm doing now is getting the weigh from the scale that use RS-232 port and post it into the website then press submit and the data will be saved into the server.
  I also study how to get the value from these port using the java API called javax.comm. However, I think it just work on the server, and could be work for one computer. that's the problem. therefore, I want to make a website that the client computer can access to the website and weigh the scale then save it into the server. So, how can we do it? Does javascript work on it?  </p>
  
  <p>thanks :)</p>
