From 78d4ee9336b523d71b321fb8a0b3b19129563dc2 Mon Sep 17 00:00:00 2001 From: Kai Vehmanen Date: Fri, 1 Oct 2010 16:04:15 +0300 Subject: [PATCH] isimodem: Add support for audio settings The audio state is mapped directly to isimodem's call server status indications. When active, the modem speech path should be opened, and when closed, the modem speech path may be closed. --- Makefile.am | 3 +- drivers/isimodem/audio-settings.c | 150 ++++++++++++++++++++++++++++++++++++++ drivers/isimodem/isimodem.c | 2 + drivers/isimodem/isimodem.h | 3 + 4 files changed, 157 insertions(+), 1 deletion(-) create mode 100644 drivers/isimodem/audio-settings.c diff --git a/Makefile.am b/Makefile.am index a4888fb..cb81ee9 100644 --- a/Makefile.am +++ b/Makefile.am @@ -128,7 +128,8 @@ builtin_sources += $(gisi_sources) \ drivers/isimodem/gss.h \ drivers/isimodem/gprs.c \ drivers/isimodem/gprs-context.c \ - drivers/isimodem/gpds.h + drivers/isimodem/gpds.h \ + drivers/isimodem/audio-settings.c builtin_modules += isigen builtin_sources += plugins/isigen.c diff --git a/drivers/isimodem/audio-settings.c b/drivers/isimodem/audio-settings.c new file mode 100644 index 0000000..ce020bc --- /dev/null +++ b/drivers/isimodem/audio-settings.c @@ -0,0 +1,150 @@ +/* + * + * oFono - Open Source Telephony + * + * Copyright (C) 2010 Nokia Corporation and/or its subsidiary(-ies). + * + * This program is free software; you can redistribute it and/or modify + * it under the terms of the GNU General Public License version 2 as + * published by the Free Software Foundation. + * + * This program is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
