The sms-python program makes use of the 'libmm-glib' library through GObject Introspection to talk to ModemManager. The program will: * Detect whether ModemManager is found in the bus * Prepare SMS properties object with the provided Number and Text. * Loop through each modem found in the system, and for each: ** Create a SMS ** Send the SMS The output will look like this: $ ./sms-python "+1234567890" "hello there, how are you?" /org/freedesktop/ModemManager1/Modem/0: sms sent Note that the program requires ModemManager and libmm-glib to be installed in the system and the introspection typelibs available in the standard paths. Have fun!
