1. Скачать последнюю версию: http://code.google.com/p/java-simple-serial-connector/downloads/list

2. Извлечь из архива файл `jssc.jar` и положить в `jroboplc/jar/libex`

Решение - перекомпиляция нативной библиотеки libjSSC-2.5_x86.so:

    cd jSSC-2.5.0-Release/src/cpp/_nix_based
    g++ -m32 -O3 -s -I$JAVA_HOME/include -I$JAVA_HOME/include/linux -fPIC jssc.cpp -shared -o libjSSC-2.5_x86.so
    cp libjSSC-2.5_x86.so /home/user/.jssc/linux/libjSSC-2.5_x86.so
