How to send file over serial port in Windows Command Prompt
提问by James Jason
I'm trying to send files over a COM port, but failed every time.
我试图通过 COM 端口发送文件,但每次都失败。
First, I configure a serial on each machine like this:
首先,我在每台机器上配置一个串口,如下所示:
MODE COMx:115200,N,8
where x is the COM port number.
其中 x 是 COM 端口号。
After this I'm trying to do:
在此之后,我正在尝试做:
COPY file.zip COM1: /B
and the reverse on the receiving PC.
而在接收 PC 上则相反。
In most cases I've gotten a broken archive. But last tries gave me nothing at all - first PC says that the file was sent, but the second is just waiting for data. Is there somebody who knows how to solve this?
在大多数情况下,我得到了一个损坏的存档。但是最后一次尝试什么也没给我 - 第一个 PC 说文件已发送,但第二个只是在等待数据。有没有人知道如何解决这个问题?

This works for me to send a binary file to an Arduino :
这适用于我将二进制文件发送到 Arduino :
mode COM21 BAUD=115200 PARITY=n DATA=8
copy yourfile.txt \.\COM21
Notice the \\.\
which is mandatory for port numbers >= 10, and can be used too for port numbers 1-9.
请注意,\\.\
对于端口号 >= 10 是必需的,并且也可以用于端口号 1-9。

You need to specify /B for binary file after the .zip file (or whatever else it is) as well as at the end of the command line. e.g. COPY ABinary.File /B COM1 /B
otherwise it will stop at the first non-text ASCII character.
您需要在 .zip 文件(或其他任何文件)之后以及命令行末尾为二进制文件指定 /B 。例如,COPY ABinary.File /B COM1 /B
否则它将在第一个非文本 ASCII 字符处停止。
