It can be notoriously difficult to configure, often requiring precise placement of javax.comm.properties . It has known limitations with 64-bit Windows and is not truly cross-platform without bundling separate native libraries for each target system. It has known limitations with 64-bit Windows and

Enables communication with external hardware like modems, barcode scanners, and custom sensors.

While it was once a stable and flexible solution for Java-to-hardware communication, javax.comm should be avoided for new projects . It is extremely difficult to set up on modern systems, and superior, actively maintained libraries are readily available.
