Creating Virtual Serial Comm port

My problem may look very trivial to u. But I am struggling since one week in search of info.I basically want to develop a Com port redirector which redirects TCP/IP input into physical/logical(virtual) com ports. Here logical means ports say COM5 to COM256. Is it required to write a device driver to do it. I think yes . If so how I can proceed. Is there any site where I can get source code to do this?. I am struck with creating virutal port. If u can help me in that rest of the things I can manage.
Thanks in advance
