Serial interfacing requires a standardized API with platform-specific implementations, which is difficult for Java. Unfortunately, Sun didn't pay much attention to serial communication in Java. Activex Viewer Download there. Sun has defined a serial communication API, called, but an implementation of the API was not part of the Java standard edition. Sun provided a reference implementation for a few, but not all Java platforms.

Particularly, at the end of 2005 Sun silently withdrew JavaComm support for Windows. Third party implementations for some of the omitted platforms are available. JavaComm hasn't seen much in the way of maintenance activities, only the bare minimum maintenance is performed by Sun, except that Sun apparently responded to pressure from buyers of their own Sun Ray thin clients and adapted JavaComm to this platform while dropping Windows support. This situation, and the fact that Sun originally did not provide a JavaComm implementation for Linux (starting in 2006, they now do) led to the development of the free-software library. RxTx is available for a number of platforms, not only Linux. It can be used in conjunction with JavaComm ( RxTx providing the hardware-specific drivers), or it can be used stand-alone.

When used as a JavaComm driver the bridging between the JavaComm API and RxTx is done by JCL ( JavaComm for Linux). JCL is part of the RxTx distribution. Sun's negligence of JavaComm and JavaComm's particular programming model gained JavaComm the reputation of being unusable. RxTx - if not used as a JavaComm driver - provides a richer interface, but one which is not standardized. RxTx supports more platforms than the existing JavaComm implementations.

Recently, RxTx has been adopted to provide the same interface as JavaComm, only that the package names don't match Sun's package names. So, which of the libraries should one use in an application? If maximum portability (for some value of 'maximum') is desired, then JavaComm is a good choice. If there is no JavaComm implementation for a particular platform available, but an RxTx implementation is, then RxTx could be used as a driver on that platform for JavaComm. So, by using JavaComm one can support all platforms which are either directly supported by Sun's reference implementation or by RxTx with JCL. This way the application doesn't need to be changed, and can work against just one interface, the standardized JavaComm interface. This module discusses both JavaComm and RxTx.
