h1. libsamsung-ipc libsamsung-ipc is a free software implementation of the Samsung IPC modem protocol, found in many Samsung devices. libsamsung-ipc contains the device-specific code for transport between the kernel interface and the upper layer (usually, the Radio Interface Layer) and the definition of the data structures and values used ion the protocol. h2. Development libsamsung-ipc sources are hosted at: http://gitorious.org/replicant/external_libsamsung-ipc branch @master@. It has support for both the Android build system and autotools. h2. Status The library itself is mostly complete: the actual protocol work takes places in the upper layer implementations, so only new devices support is left to be added. h2. Tools libsamsung-ipc ships with some tools to ease development. h3. ipc-modem ipc-modem is a deprecated tool that was used at the beginning of the work for talking to the Nexus S modem. It implements basic functionalities (mostly SIM unlocking and network registration), using libsamsung-ipc.
usage: ipc-modem 
commands:
	start                 boot modem and start read loop
	boot                  boot modem only
	power-on              power on the modem
	power-off             power off the modem
arguments:
	--debug               enable debug messages
	--pin=[PIN]           provide SIM card PIN
h3. ipc-test ipc-test is a very minimalistic tool that simply boots up the modem and receives messages as they arrive. It is intended to ease boot code development by providing a standalone binary.
