From 9df92e6369138764ce7bd44edbb307d98e9d72fd Mon Sep 17 00:00:00 2001 From: Erik Faye-Lund Date: Tue, 4 Dec 2012 09:10:39 +0100 Subject: [PATCH] compat/terminal: factor out echo-disabling By moving the echo-disabling code to a separate function, we can implement OS-specific versions of it for non-POSIX platforms.
