音视频矩阵的串口控制程序，可以实现8进四出的控制。同时提供了udp监听，接收网络命令，实现网络上控制音视频矩阵。需要用到著名的trayicon控件和mscomm控件-audio and video matrix of Serial control procedures can be achieved eight into four control. While providing udp eavesdropping, the receiving network orders network control audio and video matrix. The need to resort to the famous trayicon controls and controls mscomm
