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.[[BR]]

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): 

{{{ ./adb shell ipc-modemctrl start --pin=1234 }}}

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!

[6] Registered with network! Got PLMN (Mobile Network Code): '20810'

[I] Registered with network successfully!

[6] Registered with network! Got PLMN (Mobile Network Code): '20810'

[I] Registered with network successfully!

[I] Registered with network successfully!

[6] Registered with network! Got PLMN (Mobile Network Code): '20810'

[I] SIM Phone Book init complete

}}}

If something goes wrong, please add the {{{ --debug }}} argument to get in debug mode.

== Status ==

We were able to make the following work:

 * SMS (Rx/Tx)

 * Call (Rx/Tx) BUT NO AUDIO YET

 * GPRS 

 * SIM I/O (stored contacts, etc)

 * SIM PIN unlocking
