i want to make a web site which is able to control a hardware on a clients computer

Question

• running test on local host, the website coded with c#, is able to connect to the comm port and pass commands to the hardware just as done by hyperterminal software

• if this website is uploaded/hosted this will not work, as the server doesnot have this harware connected to the comm port needed.

  one way is to ask the hosting company to set up a special computer for me with the hardware drivers etc.

  not possible.

  • • defining hardware, the hardware is a remote control car.

so what is the solution?

Answer 1

You can create a Silverlight Out of Browser application which can run with elevated rights.
Perhaps it is possible to access the COM Port with ActiveX, too. But that would be a Internet Explorer only solution.

I found this blog where someone managed to get that working.
