主要为工控设计的，先配置好硬件所需的文件，和需要发送的命令，配合tftp，就可以自动下载硬件所需要的系统文件了。还可以自动发送命令给硬件。类似超级终端。仅共学习参考。-Designed primarily for industrial control, first configured hardware required documents, and the need to send orders, with tftp, you can automatically download the hardware needed for the system files. Can also automatically send a command to the hardware. Similar to HyperTerminal. Only a total learning reference.
