Linuxsms is a Perl script to send SMS to GSM phones. There is support for multiple servers/gateways (some servers require registration). The script has an adressbook, the ability to compress SMS, and the ability to check for new versions.

An SMS log option has been added. The login and password can be set
from the commandline. Language issues have been fixed on the gomobile
server. An everyday2 server has been added.
The grupogsm server was removed, and the gomobile server was split. Some changes
in sockets were made to make it work with old perl versions, such as 5.005.
