Terminal: Plugin: add support for [XYZ]MODEM file transfers

I'm not sure how this is related to the terminal. This sounds like a request for adding a commandline application to Windows, not a feature to the terminal.

You might be able to use WSL for this. If not, then someone would probably need to port lszrz to Windows, though this issue tracker is not the place for that feature.

@zadjii-msft
I mean it needs to support sz rz like xshell.

@zadjii-msft windows terminal should support sz/rz protocol and popout dialog box, I can't reopen this issue, please reopen it, it is very useful feature.

@zadjii-msft I think rz sz is a feature for terminal not shell (e.g. WSL).
rz sz is a program running on server, and also require terminal to support it.
In macOS, iTerm2 implement it instead of bash or zsh.
Please tell us where to request that feature.

So I still don't know why the terminal would need to add support for lszrz directly. Seems to me like the lszrz package should be the one to display the file picker on windows itself, and it's not the responsibility of the _terminal_ to display that picker. I'm not sure why a terminal window needs to get involved in the implementation of a commandline application like this.

Maybe I don't understand how sz rz works? If someone can explain why I'm wrong, I'll be happy to re-open and investigate. But this just sounds like an application that needs to be ported to Windows on it's own, and the terminal doesn't need to ship with itself.

@zadjii-msft
As a user, I don't really know what happens.

If I want to send a file from server to laptop,
I just run sz -be filename on linux (via Terminal, via shell, via ssh). This means I need to install lszrz on server.
And something should let me select where to put it, then receive and save it on my laptop.

Other Terminal do this, so I think Windows Terminal should do it too.
e.g. iTerm2 on macOS, SecureCRT / XShell on Windows

@zadjii-msft
lszrz don't display the file picker on window.
Instead, people are required to run sz/rz on both sides.
This post show what should people do without using a terminal. And this really hard to do for users.

Terminal should support lszrz (and lszrz is required to be installed on PC).
Terminal is ONLY a UI of lszrz.

lszrz is backgroud program, it can't dispaly the file picker. Something(e.g. Terminal) should find a place and run sz/rz command on laptop.

and it's not the responsibility of the terminal to display that picker.

So do you think user should be responsibility to display that picker?
ALL OTHER TERMINALS DO! (out of box or need some configure.)

I'm reopening this one and putting it on the infinite backlog.

@qin-nz: We're not going to do this ourselves, but it is a valuable feature and it would be good to think about it when plugin support is written (#555)

@zadjii-msft: This is a weird/interesting thing. lszrz is a package that implements the [XYZ]MODEM set of protocols, and is typically used for transferring files over serial connections to remote machines. The deal, though, is that that data must either be multiplexed-with or totally replace the _tty stream_. It's the terminal emulator's job to stop sending user input and waiting for connection output and instead send encoded file data packets and wait for ACKs (or the other way around.)

lszrz only includes the client portions that "send a file to the terminal" or "receive a file from the terminal," and the terminal needs to be complicit.

[zadjii-msft]

Oh my god, that's insane. Well yea of course I didn't understand that, that's a totally different style of application than anything I've ever heard of before. I'd think there would be a better way of doing this, such that the Terminal application didn't have to be directly involved in this process (maybe using a pty or something) but hey if that's how it works, that's how it works.

Sounds like a perfect extension scenario.

As https://github.com/microsoft/terminal/issues/1602 referred, Zmodem needs a plugin mechanism to implement.

[jackmin]

Hey,
Do we have a plan to have this feature?

[DHowett-MSFT]

This is on the backlog and we think it would be good to revisit when we support plugins. I can’t commit engineering time to it right now :)

terminus has already have these features including plugin-supporting. So for now I will use terminus.

any update？

[DHowett]

If there had been an update, you would have received an e-mail.

I need it!

If you approve it , please give me a thumb.

[zadjii-msft]

Please do not unnecessarily bump this thread. There's a perfectly good button for showing your support for this feature request that _doesn't_ send an email to everyone on the thread:

Please pay attention to this detaill:

sz/rz use zmodem to trans files between current terminal connecttion,
Don't care about the connection method (ssh, or telent, tty, serial Or something can trans terminal sequence)
it need to run sz & rz on each side of the connection.
not like scp create new connect, librzsz only use current connecttion, and it no ability to run sz/rz on each side,
without terminal help it can't be done, not they don't want to do it.
it just show some special char sequence to terminal (or connection layer program), some thing like this:

$ rz | hd
rz waiting to receive.00000000  2a 2a 18 42 30 31 30 30  30 30 30 30 32 33 62 65  |**.B0100000023be|

also there are some cli tool do the sz/rz support:

• zssh: a ssh client, (so only work with ssh connection), use special shortcut key to switch to peer side of current connection.
• screen: screen manager with VT100/ANSI terminal emulation

but cli tool user experience is not good.

i need this

[PICKQUE]

when i ssh a linux terminal , the sz / rz will failed. already fix it ??

[dolorain]

when i ssh a linux terminal , the sz / rz will failed. already fix it ??

not yet, checked their road map to 2.0. the terminal will not support the sz/rz at least until summer in 2021.
in theirs projects the command rz/sz belong to the thrid party tool xyz-modem. and they do not have a timeline for when they will support which one of the third party tools.

I also hope to have this feature.
