It provides implementations for the two virtual funtions input_bit and input_byte and, except for constructors, its public interface is inherited from the base class. When the port is constructed a buffer and buffer length is specified. Data is pulled from the buffer as the port is read.  When the end of the buffer is reached subsequent reads loop back to the beginning.   Public methods are:  IPortFromRam (char*, int);    The first argument specifies a buffer.  The second argument    specifies its length.*/#endif
