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
