Send sms using dongle by python code

In windows,

if its connect all is well.
then take run and type %appdata%
go down and open the .gammurc file and copy the content to the notepad and save it on a accessible location.




In linux,

install python-gammu using following
apt-get install python-gammu
Linux dont need python3. It should be run in python2.7
you can find the dongel connected port, just run dmesg right after you connected the usb dongel. there you will see it has connected to /dev/ttyUSB0 or something like that port. Some times this port may have converted to several ports in dmesg log. Get the last port in the dmesg log. use this port to include in .gammurc config file. contents are same as windows .gammurc file only replace the COM port with relevant /dev/ttyUSB port.
Note : If dongel seems to be not detected try disabling mobile connections in network settings.
