批处理能操作串口吗？

如题
想向串口1发送一个小的二进制文件，有什么命令能实现吗？

类似串口调试助手和超级终端。但我要自己设定间隔时间，自动上传。

pudn 下载的 SerialCmd 源代码，共享者的介绍是：

命令行串口工具这样就可以通过在Windows下用记事本编辑bat批处理文件我灵活的向串口发送和接收数据，简单点他就是一个命令行的串口调试助手，这样就支持bat比较灵活．可以批量向单片机或者ARM , DSP 发命令-Serial command-line tool can then be used in the Windows Notepad to edit the next bat batch file I am flexible to the serial port to send and receive data, a simple point, he is a serial command-line debugging assistants, so that support more flexible bat . Can bulk to the single-chip, or ARM, DSP order

gcc 编译通过，共享出来，免得你们没分下不了，里面定死了端口和文件，自己仿着改吧：
