I have 2 Terminals open, in one is a Python Terminal Chat client running(pt3).
I want to sent text from the other terminal(pt2) to the chat.
It does write the text to pt3 but pt3 dosent ‘see’ the text.
If i send over “hallo world” it prints on the terminal but dosent show up in chat.
A PTS is a single character device. Writing to it causes output to appear on the terminal buffer, reading from it reads from the input buffer. So, writing to it like you do from a separate shell effectively does the same as calling print() from python which has it as inherited stdio. There is a way to write to a PTS input buffer but it’s not straightforward and works in a completely different way. Use something like tmux instead, or better, sockets.
Time to dive into the wide world of VTTYs. I believe you’re writing to pts3’s output buffer - writing to its input buffer is a different virtual device / may be a process descriptor, I’m not sure. Look into the history of vttys and it should start to make sense.

My first thought was, can you flush the buffer?
Just guessing here but could it be because you haven’t set up correctly pt2 as stdin for pt3, try to invoke the command as

thank you!
tmux did thr tick for me
