通过串行端口传输文件
我正在尝试通过串行端口发送文件。我尝试以bash脚本发送picocom命令。但是，该设备写下了选项菜单。当它到达文件传输步骤时 - 它写出“ C”，直到发送文件为止，然后进行握手并进行转移。使用脚本，我无法发送击键“ CA”和“ CS”来获取“ ***文件：” Picocom的提示。我可以手动做。我什至尝试了Bash和Python和Pyautogui的组合，以击中击键，Bash Echo Command发送了Kex版本的Kex版本。我什至尝试通过脚本和STTY发送“ SZ”命令。所有这些尝试都没有成功。
因此，我切换到Python，然后尝试了 xmodem库pypi.org/project/xmodem/“ rel =” python中的nofollow noreferrer“>”。我应该使用ymodem。我认为库中的“ Ymodem批处理传输会话”将完成这项工作。调制解调器命令命令始终错误，而未发送文件。
Read Byte: b'C'
Put Byte: 133
Read Byte: b'C'
send error: expected ACK; got b'C' for block 1
Put Byte: 133
Read Byte: b'C'
send error: expected ACK; got b'C' for block 1
我该如何解决？
I am trying to send a file via serial port. I tried sending picocom commands in a bash script. However the device writes out a menu of options. When it gets to the file transfer step - it writes out 'C' until a file is sent, after which it does the handshake and proceeds with the transfer. With the script I am not able to send the keystrokes 'C-a' and 'C-s' to get the '*** file:' prompt of picocom. I can do it manually. I even tried a combination of bash and python and pyautogui for the keystrokes, bash echo command to send the hex version of the keystrokes. I even tried sending 'sz' commands through the script and stty. All of these attempts were unsuccessful.
So I switched to python, and tried the xmodem library in python. I am supposed to use ymodem. I thought the 'YMODEM batch transmission session' in the library would do the job. The modem.send command always errors out with the file not being sent.
Read Byte: b'C'
Put Byte: 133
Read Byte: b'C'
send error: expected ACK; got b'C' for block 1
Put Byte: 133
Read Byte: b'C'
send error: expected ACK; got b'C' for block 1
How can i get around this?

最终最终使用了Python和Bash -Python的组合，用于串行通信和解析二进制文件的文件名，以及Bash
Stty和sb命令，用于传输二进制文件。Finally ended up using a combination of python and bash - python for serial communication and for parsing the file names of the binaries, and, bash
sttyandsbcommands for transferring the binaries.
