Abstract
Today, society is very modern, with the keeping growth to information, kinds of equipments can connect with computers. The traditional concurrence interface technology becomes the bottleneck of improving the data transmission speed, However, the simplest method use serial communicate technology. The time of existence of serial communication by letter has been long, with the technology developing, it is not replaced yet, and the applying range is more and more broad. The Topic through "The realization of communication about bmp form image based on serial port" realizes the bmp photograph form and the information data transmission according to the prescribed form. Using C++ Builder to develop the environment design procedure for the system. The data is checked by CRC during delivering, in order to insure whether the data deliver is correct and succeed or not.
Keywords：C++ Builder，serial communication，picture format of bmp，CRC check
