From a79db45fa54e2420c9fe977a6a5835c466888b5a Mon Sep 17 00:00:00 2001 From: Samuel Thibault Date: Sun, 1 Nov 2020 19:39:13 +0100 Subject: speakup_dummy: log about characters received by the dummy driver The dummy speakup driver is used to check that speakup is working properly, without the need for actually owning the hardware. Some drivers require receiving characters, so we need a way to check that this is working properly.
