 * Description       : An abstract class for general byte-by-byte communication.
 *                     Serialport, USB, TCP/IP or similar implementations can be derived
 *                     from this class to create a technology-independent
 *                     communication interface.
 *
 *                     This abstract class does not provide any constructor as it is
 *                     too specific for this generalized class. Derived classes should
 *                     implement their own constructors for specific communication devices.
