Serial communication library for Scala, designed to be reactive, lightweight and easily integrable with Akka applications. See the website for a guide.
- Reactive: only does work when required (no constant polling of ports or blocking IO)
- Integrates seamlessly with Akka
- Portable to POSIX systems
- Watchable ports: react to connection of new device
- Compatible with Reactive Streams
Since hardware is involved in serial communication, a Scala-only solution is not possible. Nevertheless, the native code is kept simple and minimalistic with the burden of dealing with threads left to Scala. The code aims to be POSIX compliant and therefore easily portable.

Website source code is in the git branch 'gh-pages'.
Detailed documentation on building flow is available on the website (or, equivalently, in developer.md).
Since flow integrates into the Akka-IO framework, a good resource on its general design is the framework's documentation.
This project is also an experiment on working with JNI and automating build infrastructure.
