serial port - on web site?

[wence]

Is it possible for a serial port function to be accessed from a web browser? So that the user can access the data of certain device through serial port on web site.

Sure. SerProxy is one program that maps TCP<->Serial. It's pretty trivial in VB. Open a serial port and open a TCP port. When you get data on one, send it out the other. Add bells and whistles (like user-selectable ports on both sides).
