From b66201f76143391cc9b81d9c419919b9fd914a24 Mon Sep 17 00:00:00 2001 From: Dave Barach Date: Fri, 22 Sep 2017 13:34:39 -0400 Subject: Fix vpp "unix interactive" when running under emacs + gdb In this specific corner-case setup, ioctl (0, TIOCGWINSZ) returns window height = 0 and width = 0. Rather than declaring the terminal to be non-interactive, set the window size parameters to 80 x 24.
