 *  
 *  
 *  DESCRIPTION:
 *     Contains definitions for TAP class
 *
 *
 *  NOTES:
 *     1. Additional operations (update() and realize()) were added to increase
 *        the speed of communication with parallel port. You should setup global
 *        buffer size for these operations during the invoking of class constructor
