Hi there: Running mac OSX Lion, using Parallels, I imported my previous XP machine and it works great. E-managaer and Stratagy VM Manager both run.
E-manager can talk to my CIX 40 over the IP network fine, but I can't seem to get the US-R 56K modem working via a Keyspan USB to serial adapter. The modem will dial in, and try to connect, then just drops the call. This happens with Stratagy VM manager too.

I have other softwares running though this setup for other types of systems and it works fine.
