Installing Java serial port support

To use the CheckReader Java(TM) class with a check reader, install the Java Communication API version 2.0. by following its accompanying instructions. (This API is sometimes identified as the Java SerialPort (COMM) optional package.) This package may be downloaded from the Java Communications API web page (java.sun.com/products/javacomm/) and should be installed on the machine that is physically connected to the reader device.
