Re: asp.net serial port

Why would you want to use a serial port from a web application?

My first response would be 'you can't' because ASP.NET is primarily a
server side language that doesn't have regular access to the clients
machine hardware. But, my question is WHY would you need to access the
serial port? There might be an easy way if we knew what you were
wanting to do.

RE: asp.net serial port

In server side code you would do this as you would with a stand alone. You
would use the SerialPort class. There is a couple (at least) warnings
though. Two users on your website might have trouble hitting the serial port
at the same time. Permissions to the device on the other side of the port
may be an issue as the website typically will use restricted permissions.

Re: asp.net serial port

Hi,

You can do this with an ActiveX control (NETComm.ocx from my homepage, for
example), and JavaScript to access the control from code behind on the HTML
page that hosts the control. I have example code in my book (very
simplified) as a starting point. See below.
