libsamsung-ipc

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).

ipc-modemctrl

ipc-modemctrl is the tool that comes to test libsamsung-ipc. It currently implements 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:
<pre>
[I] Got SIM PIN!
r0 Starting modem on FMT client
r1 Starting modem_read_loop on FMT client
r2 Phone is powered up (LPM)!
[I] SIM card found
[I] SIM is initializing
r3 SIM init complete
r4 Modem is ready, requesting normal power mode
[I] SIM card found
[I] SIM is initializing
r3 SIM init complete
r5 Modem is fully ready
[I] Registered with network successfully!
r6 Registered with network! Got PLMN (Mobile Network Code): '20810'
[I] Registered with network successfully!
r6 Registered with network! Got PLMN (Mobile Network Code): '20810'
[I] Registered with network successfully!
[I] Registered with network successfully!
