JavaSerialPortInterfaces

There are various Java Serial Port Interfaces.

RxTx

RxTx has been around for a long time. Ptolemy used it many years ago as part of the X11 interface.

• The original maintainers of RxTx at http://rxtx.qbang.org/wiki/index.php/Main_Page are dormant.
• https://github.com/NeuronRobotics/nrjavaserial - "This is a fork of the RXTX project that uses in jar loading of the native code." As of February, 2017 active 4 days ago.
  • nrjavaserial (ptexternal wiki) Notes about building.
• RxTx - ptexternal wiki
  • RxTx Hanging

Serialio.com's Java Serial Port

• Serialio.com's Java Serial Port product
• licensing - This is a commercial product where they charge developers, but don't charge for deployment. We probably could not include the jar file in our tree and we would need to buy a license for each developer. Mac OS X licenses are $49.95 each, which is not bad.

jSSC (Java Simple Serial Connector)

• https://code.google.com/p/java-simple-serial-connector/ - Code.google.com page that is no longer being updated
• http://search.maven.org/#artifactdetails|org.scream3r|jssc|2.8.0|jar - Maven.com page for 2.8.0 from March, 2014.
• https://github.com/scream3r/java-simple-serial-connector - Github, last updated in January 2014

Device I/O

• https://wiki.openjdk.java.net/display/dio/Main - Last update for the wiki was September, 2015.
• http://mail.openjdk.java.net/pipermail/dio-dev/ - Mailing list. (Traffic from this month, December 2015).
• Under Mac OS X, to download, I did:
  sudo -i port install mercurial

  [$[Get Code]]
• As of December, 2015, this seems to only support the Raspberry PI.

Jim Connors blog, "Java Serial Communications Revisited"

• Jim Connors, "Java Serial Communications Revisited," June, 2014. - This is a good summary of the state and mentions the above resources, though it is a bit out of date. Worth a read.

PureJavaComm

• http://www.sparetimelabs.com/purejavacomm/purejavacomm.php - Overview
• purejavacomm (GitHub) As of February, 2017, last update was in December, 2016.
• #67 JVM crash when hardware in use disconnected - PureJavaComm is promoted as fixing a nrjavaserial crash
