From 7c336f9fe53b1a500f21241841c7bf4267c7ee14 Mon Sep 17 00:00:00 2001 From: Alexander Graf Date: Tue, 29 Aug 2017 13:38:18 +0200 Subject: [PATCH] console: add question-mark escape operator Some termcaps (found using SLES11SP1) use [? sequences. According to man console_codes (http://linux.die.net/man/4/console_codes) the question mark is a nop and should simply be ignored. This patch does exactly that, rendering screen output readable when outputting guest serial consoles to the graphical console emulator.
