you user
I have to re-implement an existing system from scratch.
At one point, when the user navigates to a certain web page the server must read data from the user's serial port.
Currently, the web page has an ActiveX control; when the page is loaded the ActiveX control calls into a COM DLL on the user's PC which reads data from the serial port.
The system is 10 years old. Is there any "better" way that I could implement this?
