    Interested in your patches to rxtx.. but the windows .dll here does not work for me. tried compiling from your source, compiles identical .dll here. tried compiling from cvs, also gives non working dll. but, your version of 2.2pre3 works fine. so.. any idea what is going on? does the pre5 dll here work fine on other windows systems? any clue appreciated.

    I really wish I could elaborate on “does not work”, but it just.. fails silently.. no errors or warning but the rxtx objects in the java program can’t be initialized, class not found.. exact errors as when there is no .dll at all in the path. I tried enabling debugging in the makefile, made a .dll 50k larger but same silent failure. thanks for letting me know it does work on something at least :) now i will try to find the difference here.

    just a note to say this does work very fine in a winxp VM running on the very same vista machine it wont load on. maybe just a problem with that box. if it is only a few words could you say how to make a 64 bit build? i tried changing obvious things in the makefile but no joy… i am !aware to windows :(

    I guess I compiled the 64b version, you can get it from my github site:

    sorry to bother, i think this is the pre2 64bit .dll.. it matches size with the one i have for pre2, claims to be pre2 in version warning, and performs as poorly as the pre2 i have :) did you ever build one for win64 with your latency patch? this is what i am trying to find, create, or beg..

    Any chance you could provide some instructions for updating the library on Mac OS X systems? I’m having some latency issues with an Arduino project. Thanks, great post!

    I need to modify the rxtxserial.dll to increase the answer in a sp├ęcial case of smardcard communication.
    what environement have you used to gererate what we can found in the build folder? (enviroment , compilator ..)

    wow, thank you! I’m using Processing to communicate to industrial motors where quick feedback is wanted.
    I got down from 20 to 5 ms for answers !
    I hope the processing team adopts your library.

    Is there any solutions for Ubuntu?
