gsmd

gsmd is the GSM daemon running in background of the GTA01 phone, managing the actual 'phone' part of the phone :)

Usage

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

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

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

libgsmd-tool is a small demo applicaiton that can be used to demonstrate the usage of the libgsmd API.

Usage

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

        o       Power Off

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
