Add SIMCOM support. Implemented using SIM5216E module and ofono 1.12. - based on SIM5215_SIM5216_ATC_V1.18.pdf documentation ; - SMS and GPRS work (in the same time) ; - SIM card presence check ; - use GSM charset ; - use 115200bps, 8 bit data, no parity, 1 bit stop, no data stream control for tty configuration ; - flight mode support ; - No voice part (because I can't test it). --- ofono-1.12.orig/Makefile.am 2012-04-20 21:06:29.000000000 +0200 +++ ofono-1.12/Makefile.am 2013-01-21 17:17:48.089627277 +0100 @@ -371,6 +371,9 @@ builtin_sources += plugins/samsung.c builtin_modules += sim900 builtin_sources += plugins/sim900.c +builtin_modules += simcom +builtin_sources += plugins/simcom.c + if BLUETOOTH builtin_modules += bluetooth builtin_sources += plugins/bluetooth.c plugins/bluetooth.h --- /dev/null 2013-01-28 10:34:59.843091650 +0100 +++ ofono-1.12/plugins/simcom.c 2013-02-15 16:16:38.058552544 +0100 @@ -0,0 +1,434 @@ +/* + * + * oFono - Open Source Telephony + * + * Copyright (C) 2008-2011 Intel Corporation.
