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

> src/util/libgsmd-tool -m atcmd
