This is Serial comm enhancement package for Waba SDK. It is part of Waba SDK, not Waba VM! That means it helps you develop application, not run it. Originally, Waba itself has very good serial port support, but Java classes used for writing, debugging and testing application doesn't have serial comm support. waba.io.SerialPort class is basically a "placeholder" offering no functionality. So, I have put real functionality into it. Now it is possible to test and debug waba programs with serial support under Java. For installing, just put enclosed files from src and classes directory, overwriting its current content. You should also install serial support for Java, downloaded from http://java.sun.com/products/javacomm/ Michal Hobot MichalHobot@netscape.net
