I think any search will come up rather empty, or direct you write your own TCP/IP stack and implement your own server. 

Freeware is not as free as it seems, because you get freeware support, and freeware development, which can vary. If you are using this in a serious application I would go with a trusted OPC vendor that understands has implmented OPC.  

Try MatrikonOPC's server for Modbus
