This is the first official release...it works fine with Squeak 3.2, and
technically should also work as far back as Squeak 2.9a (post Morphic alignment
updates).
On UNIX, OSProcess is required (if you want to use RemoteControl--the X10Driver
does not require it). On Windows, all you need is an FFI-enabled VM.
Make sure you have the latest VM, as older VMs had problems with their serial
port handling.
