I just compiled the rxtx v2.2pre3 library (I just call it that way, its the cvs head from 31.6.2010). There are binaries for win32, win64 (untested) and Mac OSX in the package:
1 2 3 4 5 | # file librxtxSerial.jnilib librxtxSerial.jnilib: Mach-O universal binary with 3 architectures librxtxSerial.jnilib (for architecture x86_64): Mach-O 64-bit dynamically linked shared library x86_64 librxtxSerial.jnilib (for architecture i386): Mach-O dynamically linked shared library i386 librxtxSerial.jnilib (for architecture ppc7400): Mach-O dynamically linked shared library ppc |
The maximal serial speed for MacOs X is 230400 (check the file /Developer/SDKs/MacOSX10.6.sdk/usr/include/sys/termios.h) – but I wasn’t able to communicate with my Arduino at this speed. 115200 baud works fine. Any hints how to fix this?
For your viewing pleasure, here is the changelog since v2.1.7 (Jan 29 2006):

Sweet <nate@n4te.com> http://mailman.qbang.org/pipermail/rxtx/2009-November/5482004.html regenerated gnu_io_RXTXPort.h and gnu_io_RXTXCommDriver.h; changed version string returned nativeGetVersion(); moved nativeGetVersion() to RXTXVersion; added native_psmisc_report_owner() (same as for Win32); removed unnecessary GetLastError() calls; added explicit WCHAR-to-jchar casts (and vice versa) where the compiler complains (same for LPWSTR and for "const" qualifier); adjusted some debugging messages (to also print returned error code); wrapped remaining printed error messages (and MessageBeep) into IF_DEBUG(); made printj() defined only if DEBUG; replaced trailing "n" with "rn" in printj(); replaced "I" type char with "J" one for "eis" field; replaced get_java_int_var() with get_java_var_long(); changed nativeSetSerialPortParams() returned type to jboolean; added nativeClearCommInput() and readTerminatedArray() stubs (these should be implemented in future); removed "MonitorThreadCloseLock" field usage in eventLoop(); commented out unused throw_java_exception(), get_java_boolean_var2() and removed get_java_boolean_var(); replaced Sleep(0) call with Sleep(1) one in CommEventThread() ( to make yielding a bit "more reliable" among threads with different priorities); replaced named event with an unnamed one in InitialiseEventInfoStruct() (see the note below); added new JAVAXCOMM_FRONTEND macro for convenience (if defined then PortInUseException and UnsupportedCommOperationException are used "javax.comm" package (old behavior) else from "gnu.io." one (default)); commented out DllMain() definition (since it does no action, only consumes resources); updated Readme.

Edit 8.2.2011:
- librxtx works fine with the baudrate 921600.
- Make sure your /System/Library/Java/Extensions/ directory does not contain old versions!
- do not rename old version, delete them!!!!

your 64-bit works fine but you need to update RXTX Version in the jar file. Currently a warning is given as follows:
WARNING: RXTX Version mismatch
Jar version = RXTX-2.2
native lib Version = RXTX-2.2pre3
It would be nice if this is corrected. Keep me updated please.
I know – it’s because the native library is not yet final but the java lib is. So no need to fix this.
For some reason when I try to use the 2.2 library my JVM crashes when it goes to initialize the RXTX drivers. Any Idea what would cause this? This is on Win32 XP.
I am using 2.1.7 Ok.
Hi, I am having problems with rxtx 2.2pre2 when i have more than two open serial ports at the same time. The system crashes and closes:
A fatal error has been detected by the Java Runtime Environment:

I tried to update to your 2.2pre3 version but it didn’t solve the problem. Do you have any idea what could be happening?
Its a bug in the c part of the library- try to send the bug report to the rxtx mailing list.
