Hi

I need to create a web page to access a serial port from any computer
around the world via IP.

Programming the Port is not a problem.
How can I access any PC in the world ?

You can do it via socket programming, remoting, or some other method (web
services, Windows Communications Framework, etC).

Hi,

Creating a web service would be the most straight forward approach, I think
(and would provide answers for most security issues).  You would have to
handle port contention if the remote PCs need to send data (I have examples
of this sort of thing in my book, though for earlier version of VB, and not
over the web).  It all they remote devices need to do is to READ data, then
port contention is not an issue, and the service would be fairly simple.

This also is possible over TCP/IP (example, see RemoteComm on my homepage).
However, the port would have to be open, or you would need an more complex
access method), and multiple simultaneous connections can be painful.
