How do I use ZModem in Visual Studio Code?

Question

Is it possible to configure vs code to support the ZMODEM protocol? I could use xshell to download files with sz command, but when I try to use sz in vs code, here it returns some random number.

(base) [alpha@hpc03 newfile]$ sz INCAR
�*B00000000000000

I use Remote-SSH extension in vs code to connect to the Linux system.
My question is:
Is there any extension or configuration method that would allow me to use sz in vs code?

Answer 1

As far as I know (I looked, didn't find anything) there's no existing extension or method to use the ZModem protocol with VSCode. However, there's a pull request from 2017 that adds support for it to Xterm, which is the terminal display VSCode uses. As indicated in this mentioning issue the VSCode developers would need more information.

As far as an extension goes, if you or anyone reading this wanted to make an extension for this purpose, you could use this ZModem.js implementation of the protocol in Javascript, and write the extension yourself, or do something similar.

From the Remote-SSH docs

VS Code will look for the ssh command in the PATH. Failing that, on Windows it will attempt to find ssh.exe in the default Git for Windows install path. You can also specifically tell VS Code where to find the SSH client by adding the remote.SSH.path property to settings.json.

Maybe you can include Xshell somehow this way. Or find a windows version of zssh (not this from the Ziti project) and it could work. Another candidate is SecureCRT. (via). Probably these rich GUI apps are not embeddable as simple CLI programs, though. Which would be a useful feature in this case.
