VM socket communication is superior to VM serial communication in every way. Unfortunately at this time only Linux supports them. Fortunately, that's 99% of PBot's userbase. If you're not using Linux or if you're using an older Linux that does not support VM sockets, the PBot VM scripts will gracefully fallback to using the serial connection. You may explicitly disable VM socket connection attempts by setting PBOTVM_CID=0.
