Directory tracking not working with mosh

[greened]

I've been using emacs-libvterm successfully for a while with ssh. Recently I tried mosh and suddenly remote directory tracking doesn't work. find-file doesn't recognize that I'm on a remote host and doesn't present a TRAMP remote path. I have not changed my prompt.

I'm pretty sure this isn't a libvterm problem per se, but I'm not sure how to go about diagnosing the issue. Any suggestions?

Directory tracking has to be configured on the remote server as well. To do this, you have to print out your username, hostname, and folder with the escape code 51;A. This is the same for (ansi-)term, so if you find some examples for that, it should work here as well.

I have done all that and it works great with ssh. Switching to mosh causes it to fail.

Sorry, my bad. I got confused about what mosh is.
A quick search brings me to this PR: mobile-shell/mosh#637
This would add support to OSC 51 (I think), which is what we need.

Doesn't that issue talk aabout OSC 52, not 51?

I also filed an issue with mosh about this and will update it with your information. Thanks!

Yes, the issue is for OSC 52, but (very) quickly looking at the code in the first post my impression is that other OSC would be implemented as well.

I'm going to try to take a crack at implementing it in mosh.

And...I got stuck right away. I took the existing patch in mobile-shell/mosh#637 but like the author, don't know how to actually send the OSC through to the terminal.
