Pressing F1 to transmit voice does not work, see screenshot

I managed to compile on raspberry pi, it does join my server
However when I press F1, it prints [11~

and does not transmit

I can receive sound, it seems to work, but I just can't speak !

Ok, to change the F1 behaviour in putty

Go to settings and set Xterm R6 and now the F1 works as intended

Unfortunately, now I have discovered barnard lacks the feature of Transmit on voice activity
I really need this feature, so I will have to try another terminal capable mumble client

Next is talkkonnect, if that doesn't work out then it's going to be mumble client with framebuffer
