I have been searching high and low for a way to get my silverlight application talking to the COM port on my local computer. Has anybody out there been able to get Silverli
There's no access to computer resources, but you can communicate with sockets. So it's possible to have your users install an application which listens on a port and communicates with a COM port.
Why are you trying to communicate with a COM port? If you're looking for webcam support, take a look at Jonas's hack which uses Flash to get webcam input: http://jonas.follesoe.no/WebcamInSilverlight2MacGyverStyle.aspx
