Framebuffer Scrollback Buffer

To increase the size of the framebuffer scrollback buffer, use the fbcon kernel parameter:

fbcon=scrollback:Nk

Where N is a number. The default: N=32k

Dealing with a serial TTY smaller than your terminal

• Open tmux
• Press Ctrl+B q to see the tmux pane size (e.g. 190x41)
• Open the serial connection (e.g. with minicom or screen)
• Set TTY rows and cols:

  stty rows 41 cols 190

• Profit
