SUDT SerialNull 是一款虚拟串口的专业配置工具，主要用于模拟RS232串口的虚拟连接，适用于串行口相关的软硬件开发、测试工程师。在系统中所创建的虚拟串口在功能以及使用上与真实物理串口一致。可以在不占用真实串口的情况下，创建任意数量并互为连接的纯虚拟串口对。 ,SUDT SerialNull is a virtual serial port configuration of the major instrument, mainly used to simulate a virtual RS232 serial port connection, applied to the serial port hardware and software related to development, testing engineers. In the system by creating virtual serial port in the functional and the use of on with the real physical serial line. Can not occupy the real serial circumstances, and each other to create any number of pure virtual serial port to connect right.
