Creating a COM Port Redirector over the Network

Question

I'm trying to create a windows driver that allows a standard TCP/IP socket to be used like a COM Port. I am aware of a number of existing products that do just this, but can find no reference material as to how it's actually done! I understand some of the concepts of windows drivers (bus/function/filter drivers, driver stacks, etc), and have tried reading a book on WDF, but I'm still not 100% sure on where I start if there is no actual backing hardware. If anyone has any links/pointers that will help, it would be much appreciated.

Take a look at the com0com project. They also offer an com2tcp driver. As it is open source you can go through the sources and get an idea of how it's done.

Actually this is not a driver, but an app, so it might be less helpful in your task to learn something about driver development, but anyway could be a good starter for some technical insight.
