Well, it is a full serial port. In fact if you really do just want to use it as a serial port then I recommend you forget the mouse interface and just use it directly as a serial port. Your life will be much simpler. >From Sun you can download the javacomm package >(http://java.sun.com/products/javacomm/) It allows you to work directly with >serial ports, the control lines, respond to interrupts when characters come >in, etc.
