+==== fso-gsmd ====
+The configuration file is:
+  * **''/etc/freesmartphone/conf/<platform>/fsogsmd.conf''** or
+  * **''/etc/freesmartphone/conf/default/fsogsmd.conf''**
+Man page says: //The daemon will be started automatically by DBus, once a request is send to it//; actually the daemon is started just after ''fsodeviced'' is started.
+The ''fsogsmd'' implementation is capable of **{{.:freerunner:0710-720.zip|GSM 07.10 Multiplexing}}** using the library ''libgsm0710mux'', so installing the **fso-abyss** or the previous **fso-gsm0710muxd** packages is not required.

 ==== GSM/GPRS ====
-Shuld upgrade the GSM modem firmware? Look at this page about **[[http://wiki.openmoko.org/wiki/GSM/Flashing|flashing]]**.
+=== Upgrading the modem firmware ===
+I don't need to upgrade the GSM modem firmware (see **[[http://wiki.openmoko.org/wiki/GSM/Flashing|flashing]]**) because Moko11 is the latest version available. Checked with **''minicom''** (''/dev/ttySAC0'', 115200 8N1):
+<code>
+AT+CGMR
++CGMR: "GSM: gsm_ac_gp_fd_pu_em_cph_ds_vc_cal35_ri_36_amd8_ts0-Moko11"
+</code>
+=== TCP/IP connection (GPRS) ===
+The TCP/IP connection is called GSM PDP (Packet Data Protocol) and it is handled by the FSO stack, the package providing this interface is **fso-gsmd**. The ''fsogsmd'' daemon actually uses **''pppd''** to make the connection and to create the ''ppp0'' interface.
+''pppd'' is called with some default options (search ''ppp_options'' into the source files), which don't work with the ISP provider I know. Fortunately we can override the options in **''/etc/freesmartphone/conf/GTA02/fsogsmd.conf''**
+<file>
+# Conseder also the options ktune;proxyarp for tethering.
+ppp_options = debug;115200;nodetach;modem;crtscts;hide-password;noauth;noipdefault;defaultroute;replacedefaultroute;usepeerdns;noproxyarp
+</file>
+=== Missing ppp2fsogsmd.so ===
+There was the [[http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=647078|bug 647078]] which caused this error in ''/var/log/fsogsmd.log'':
+<code>
+[INFO]  PdpPppMux <>: PDP Context Status now FREE_SMARTPHONE_GSM_CONTEXT_STATUS_OUTGOING
+[INFO]  PdpPppMux <>: PDP Context Status now FREE_SMARTPHONE_GSM_CONTEXT_STATUS_RELEASED
+[WARN]  PdpPppMux <>: PPP quit immediately; check options and permissions.
+</code>
+I had to make this symlink:
+<code>
+/usr/lib/cornucopia -> /usr/lib/arm-linux-gnueabi/cornucopia/
+</code>
+=== Exploring the FSO interface ===
+This is the service provided by the package **fso-gsmd** and the low-level driver **fso-gsmd-openmoko**, which are from FSO Cornucopia implementation.
+Making a TCP/IP connection uses the Packet Data Protocol interface. This is an example of DBus chat, using **''mdbus2''** in interactive mode.
+  - The GSM modem gets powered-on with ''RequestResource''.
+  - Register on the GSM network.
+  - APN, login and password are entered.
+  - Check PDP status and start the connection.

+mdbus2 -s -i

+</code>
+FIXME: exiting ''mdbus2'' (with Ctrl-D), the GSM device is released (and the power turned off), but ''pppd'' is not terminated, it remains running and consumes the log file.
-FIXME Check the new **fso-abyss** package which superseed fso-gsm0710muxd, chek what are the proper packages to install:
+=== Other notes ===
-  * [[http://packages.debian.org/sid/fso-gsmd|fso-gsmd]]
+FIXME The following is old stuff, superceeded by FSO Cornucopia implementation.
-  * [[http://packages.debian.org/sid/fso-abyss|fso-abyss]]
-  * [[http://packages.debian.org/sid/fso-gsm0710muxd|fso-gsm0710muxd]]
 FSO provides a nice multiplexing of GSM/GPRS. Different aplications can talk to the GSM modem concurrently and place GSM calls while running a GPRS internet connection (bandwidth will be the bottleneck!). The GSM multiplexing is handled by the **fso-gsm0710muxd** package.

 This is the DBus interface provided by FSO Cornucopia implementation (**''fso-deviced''**, version 0.9.5+git20110805-1). The interface provided by ''fso-deviced'' is not complete, so also the old ''fso-frameworkd'' is installed.

 ==== Idle notification: timeouts and signals ====
@@ Line 595: / Line 668: @@
 Idle status is one of the following: **''busy''**, **''idle''**, **''idle_dim''**, **''idle_prelock''**, **''lock''** and **''suspend''**. To prevent the device entering a state, set its timeout to **''-1''** (see the note below). If a state is disabled, the subsequent states are never reached.
