gsmd is the GSM daemon running in background of the GTA01 phone, managing the actual 'phone' part of the phone :)
gsmd is usually started as a daemon in background, but can be run in foreground mode for debugging.
The options can be queried like:
> src/gsmd/gsmd --help gsmd - (C) 2006 by Harald Welte <firstname.lastname@example.org> This program is FREE SOFTWARE under the terms of GNU GPL Usage: -v --version Display program version -d --daemon Deamonize -h --help Display this help message -p dev --device dev Specify serial device to be used -s spd --speed spd Specify speed in bps (9600,38400,115200,...) -l file --logfile file Specify a logfile to log to
If your GSM modem is attached to ttySAC0 (like in the Neo1973 Hardware, you can e.g. use:
gsmd -p /dev/ttySAC0 -s 115200
libgsmd is a library with C language API for application programs. Programs using this library can use the phone, e.g. make phone calls, receive incoming calls, register to the network, etc.
libgsmd-tool is a small demo applicaiton that can be used to demonstrate the usage of the libgsmd API.
libgsmd-tool has multiple modes.
Usage of shell mode
Shell mode provides a simple text-based command interface for making voice calls.
The shell mode can be started using
libgsmd-tool -m shell
It can be used like in the following example:
> src/util/libgsmd-tool -m shell libgsm-tool - (C) 2006 by Harald Welte This program is Free Software and has ABSOLUTELY NO WARRANTY ? # A Answer incoming call D Dial outgoing number H Hangup call O Power On o Power Off R Register Netowrk O # EVENT: PIN request (type=1) Please enter PIN: 6582 R # EVENT: Netreg searching for network EVENT: Netreg registered (home network) D03024033902 # Dial 03024033902 EVENT: Call Progress: UNKNOWN EVENT: Call Progress: PROCEED EVENT: Call Progress: SYNC EVENT: Call Progress: ALERT H # Hangup EVENT: Call Progress: DISCONNECT EVENT: Call Progress: RELEASE EVENT: Incoming call type=2! EVENT: Incoming call clip=`"03024033902"' EVENT: Incoming call type=2! A # Answer RSTR=`OK' H # Hangup RSTR=`OK'
Usage of atcmd mode
The atcmd mode is a passthrough-mode. Passthrough means that it accepts GSM 07.07 commands, passes them through the daemon to the phone, and returns you the response. this is very useful for debugging.
The atcmd mode can be started using
libgsmd-tool -m atcmd
Usage is like in the following example:
> src/util/libgsmd-tool -m atcmd libgsm-tool - (C) 2006 by Harald Welte This program is Free Software and has ABSOLUTELY NO WARRANTY AT+CPAS STR=`AT+CPAS' RSTR=`+CPAS: 0' AT+COPS=? STR=`AT+COPS=?' RSTR=`+COPS: (2,"E-Plus","E-Plus","26203"),(3,"o2 - de","o2 - de","26207"),(3,"Vodafone.de","Vodafone","26202"),(3,"T-Mobile D","TMO D","26201")'
