Ok.
thanks.
I find the API for Java Communications (java.comm) and i see some examples of applications. Very good, very good same!
i will develop application for Windows, for be used in lab enviroment (DAQ for control systems, as motor control, hidrogenionic potential control, level control, between others). My application must be have robustness (because i will use send/receive of signals and data, control using PID techniques, LGR, and, futurely, adaptative and robustness control). This application will be an educational program for digital control design. I do not see any application like this, done in Java enviroment... only in C, Visual Basic, and others. So, my ask and doubt. As for performance, and features, my need is real time control, DAQ in real time, lightness and development facilities. I domine Java, but, do not working with C for applications.
Thanks for reply.
