I found other bug using the RXTXcomm.jar version 2.1.7 in ubuntu 9.10 64 bits (maybe too using other 64bits linux distros). The write to serial port works right, but the read is wrong (JAVA error 134, Problematic frame: # C [librxtxSerial-2.1-7.so+0x8333] read_byte_array+0x43). SOLUTION: to resolv this problem download the prerelease 2.2 (http://rxtx.qbang.org/pub/rxtx/rxtx-2.2pre2-bins.zip), unzip, and copy the files to: sudo cp path/rxtx-2.2pre2-bins/RXTXcomm.jar /usr/share/java/RXTXcomm.jar sudo cp path/rxtx-2.2pre2-bins/x86_64-unknown-linux-gnu/librxtxSerial.so /usr/lib/librxtxSerial.so too add this line to your code: System.setProperty("gnu.io.rxtx.SerialPorts", "/dev/ttyACM1"); //or oher ACMx And enjoy -- librxtx-java doesn't find serial ports after upgrade to Jaunty https://bugs.launchpad.net/bugs/367833 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
