Let me add that within emacs-libpq M-x vterm it works without any problems, including on any terminal emulator outside of Emacs. https://github.com/akermu/emacs-libvterm Excerpt: term: it is a terminal emulator written in elisp. term runs a shell (similarly to other terminal emulators like Gnome Terminal) and programs can directly manipulate the output using escape codes. Hence, many interactive applications (like the one aforementioned) work with term. However, term and ansi-term do not implement all the escapes codes needed, so some programs do not work properly. Moreover, term has inferior performance compared to standalone terminals, especially with large bursts of output. Maybe that is problem. I do not know. I wish I would not need to use external dynamic module.
