The Alamin GSM SMS Gateway is a group of daemons that allows you to send/receive SMS messages from any GSM device that supports AT+ commands (GSM modems or GSM mobile phones) or supported by Gnokii. A client program allows you to send messages from any IP client. An SMTP interface is provided to allow MTAs to send SMS directly to the GSM network. IMP (Incoming Message Processor) modules allows you to extend functionality to implement banking, network administration, bd querys, etc. from a GSM mobile phone.
gnokii is a multisystem tool suite for mobile phones. It provides a library to communicate with a phone hiding the communication protocol. The library handles SMS, phonebook, calendar, phone calls, and other mobile phone capabilities. It supports Nokia-FBUS mobiles, AT-capable phones (most of the mobiles), as well as Symbian-based phones.
SMSLink implements a client/server gateway to the SMS protocol (short messages on the mobile phones). It requires the use of dedicated hardware (a serial GSM module). Both SMS emission and reception are supported, either in text-mode or in PDU-mode. It also includes an SMS to eMail gateway module. The server runs under Linux and FreeBSD and supports interactive mode via telnet. The command-line client already exists for Linux, FreeBSD, Solaris, HP-UX, and Win32. A basic Web interface is also provided.
YaPS (Yet anothewr Paging Software) is primarily designed to send message to pager devices (including cellular phones) which are able to receive SMS. It is a simple command-line driven program with a global and a personal configuration file, but the protocol implementation is kept as a seperate library. YAPS can transfer Pager Messages with UCP, TAP, and Script Protocol.
Gammu (formerly known as MyGnokii2) is a cellular manager for various mobile phones/modems. It supports a wide variety of Nokia, Symbian, and AT devices (Siemens, Alcatel, Falcom, WaveCom, IPAQ, Samsung, SE, and others) over cables, infrared, or BlueTooth. It contains libraries with functions for ringtones, phonebook, SMS, logos, WAP, date/time, alarm, calls, and more (used by external applications like Wammu). It also includes a command line utility that can make many things (including backups) and an SMS gateway with full MySQL and PostgreSQL support from the PHP interface.
