用并口通信时,只需发送仿真软件的十六进制显示窗口的第四个字节后的所有数据。 如:清全屏的十六进制显示窗口是55AA0001434C42,采用并口通信时只需发送434C42-with Parallel Communications, only this simulation software hexadecimal display window of words, after the data. Such as : a full-hexadecimal 55AA0001434C42 show window is used and only parallel communication sent 434C42

This version of the code is compatible only with the AT89C2051 due to the location of the data buffer and stack in RAM. The code may be modified to work with the AT89C1051 by relocating or resizing the buffer and stack to fit into the smaller amount of RAM available in the AT89C1051.
