Valid SNA Server for wM Mainframe

Hi all.
We are trying to install wM Mainframe, so we need a SNA Server to establish communication with our CICS.
Do you know which SNA Server are valid?
We are trying to work with IBM Personal Communications, but we are not sure it will work.
Can you help us?

Thank you very much.

Microsoft’s HIS (Host Integration Server) is what I’ve seen used.
