I'm trying to access my raspberry pi via its serial console on the gpio pins. It's working fine through a USB-3.3v serial dongle. However, there's a problem with long lines and long screens not displaying correctly. I'm running minicom in a gnome-terminal which is not set to 24x80 columns (and gnome-terminal's Terminal/1 (24x80) option) doesn't help.
It's as if minicom completely ignores the sigwinch it must be getting, and/or has no way to send that over the serial line to change the terminal type.
