FS#3170 - tty features or permissions incompatible with tmux

[openwrt-bot]

plntyk:

replicated :

on x86_64 VM: LEDE, 18.06.x, 19.07.x, snapshot
mips Malta VM (be): snapshot

on serial (-nographic) and graphic terminal

tmux does not show input/output but works

replicate:

• install tmux
• run tmux
• input/output is send to tmux , visible via a ssh connected tmux instance (which works fine)

"hotfix":
start screen then start tmux and tmux functions as expected

Install coreutils-stty, then set rows & cols to none zero values. This seems to fix the issue at the moment. Will need to investigate how to get console size and who to set it.

stty size stty rows 32 stty cols 64 stty size
