There are a couple of ways you can achieve this, but none are 'straight off the shelf'. It cannot be done directly, but you can either:<br />
<br />
* Make an applet that connects to a 'service' that interprets commands sent from the applet to the service, which in its turn writes commands to the RS232<br />
* Create a cgi script that interprets the commands given from the browser and puts commands over the RS232<br />
<br />
Remember that when you create such a thing, that there will be some network latency... so your commands will not be processed right away!

I want to make a web based controll that has buttons and when I click a certian button, it sends its corosponding code to a particular com port.<br />
My first experiement will be to try to controll my benq 8700 projector via its rs232 port. I have already aquired the 8700 rs232 controll codes from benq.<br />
now I just want to make a web based front end that will run on the computer that is connected to the 8700.<br />
<br />
Any and all help will be greatly appreciated.<br />
<br />
I am sure that many others could learn from this post after it gets some 'seasoned' answers.<br />

web based controll of rs232 and sending rs232 codes from a web page

Web development can range from developing the simplest static single page of plain text to the most complex web-based internet applications, electronic businesses, and social network services using a wide variety of languages and standards, including the familiar HTML, JavaScript and jQuery, ASP and ASP.NET, PHP, ColdFusion, CSS, PHP, Flex and Flash, but also the implementation of a broad list of standards including XML, WSDL, SSDL, VoiceXML and many more.
