A place to put frequently asked questions.
Where can I find information about how to write apps using RXTX?

On MacOS X I get a 'PortInUseException', even though it isn't?
Versions prior to 2.1-8 use lock files, which is not the MacOS X way of doing things, and therefore has issues. For this reason make sure that you have version 2.1-8 or higher, which makes use of I/O Kit. At this point in time 2.1-8 is only availble from CVS, in source form. See the section Retrieving Source Code, on getting the latest code - be sure to get the code from the 'gnu.io' branch.
Question: Can anyone who knows how please make an easy download available like the 2.1-7 version?
RxTx does not find my device, what's wrong?
There may be a number of reasons, but most often it is because your operating system can't find it either. RxTx is built upon the functionality provided by your operating system, and therefore is dependent on its limitations. For this reason find out whether your system can find the port, if it can and you stil can't work what is going on, then there may be some help on the RxTx mailing-list.
