libsamsung-ipc is a free implementation of the protocol to speak with modems found in most Samsung devices. It is the low-level library used to communicate with the modem and needs an upper-layer (RIL) to interface with the system.
libsamsung-ipc is shared between SHR and Replicant projects. It's used in both for the Nexus S.
Source code is available under the GPLv3+ at: https://github.com/morphis/libsamsung-ipc (master branch).
The library is mostly complete
ipc-modemctrl is a deprecated tool that was used at the beginning of the work for talking to the nexus S modem. It implemented basic functionalities (mostly SIM unlocking and network registration).
Usage:
usage: ipc-modemctrl <command>
commands:
start bootstrap modem and start read loop
power-on power on the modem
power-off power off the modem
arguments:
--debug enable debug messages
--pin=[PIN] provide SIM card PIN
Please run ipc-modemctrl like this (from host pc):
assuming your SIM PIN is 1234. If you don't have any SIM pin, don't pass the --pin argument.
It should go like this:
[I] Got SIM PIN! [0] Starting modem on FMT client [1] Starting modem_read_loop on FMT client [2] Phone is powered up (LPM)! [I] SIM card found [I] SIM is initializing [3] SIM init complete [4] Modem is ready, requesting normal power mode [I] SIM card found [I] SIM is initializing [3] SIM init complete [5] Modem is fully ready [I] Registered with network successfully!
