问题
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?
回答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.
