LucidControl goes JAVA I was a bit of surprised a few weeks ago that Java has only a very limited native access to the serial comports. We use the serial ports to communicate with our. ![]() These modules have analog and digital IO functionality and they are compatible with USB CDC (Communication Device Class) which means that most operating systems provide a driver which installs a virtual comport. Microsoft Windows enumerates them as a COMxx device. Linux operating systems give the devices usually names like /dev/ttyACMxx where xx is the identifier number of the port. I’m familiar with C# which provides the SerialPort class. This is supported by dotNet and also by Mono and runs under Linux as well. I used this class several times for portable applications running mostly under Windows and Linux. Because of this I expected easy access to the serial port under Java as well and I didn’t waste much thought on doing such a common task in Java. But in reality Java does not support them – at least under Microsoft Windows. In the following I will explain which options are available in order to access serial ports in Java. CommAPI – Limited native support The provides an interface to access serial ports. This sounds very good, but has one significant drawback because support for Microsoft Windows was dropped years ago and it is not possible to write portable applications anymore. Because of this severe restriction I dropped this solution without further investigation. RXTX is the first option which comes one in mind when talking about alternatives of CommAPI. It is a comprehensive and reliable interface which is used in many projects. I used this in our pre-release revisions of JLucidIo Library. Which implements classes encapsulating the functionality of our LucidControl USB IO Modules. I thought this was a good option because it is relatively easy to install and it is working reliably. So why didn’t we go for it? This has mainly three reasons: • RXTX is not pure java. The hardware dependent part is written in a different language.
