3 | 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]] |
||
4 | 2 | Paul Kocialkowski | libsamsung-ipc is shared between SHR and Replicant projects. It's used in both for the Nexus S. |

10 | ipc-modemctrl is the tool that comes to test libsamsung-ipc. It currently implements basic functionalities (mostly SIM unlocking and network registration). |
||
11 | |||
12 | Usage: |
||
13 | {{{ |
||
14 | 2 | Paul Kocialkowski | usage: ipc-modemctrl <command> |
15 | 1 | Paul Kocialkowski | commands: |
16 | start bootstrap modem and start read loop |
||
17 | power-on power on the modem |
||
18 | power-off power off the modem |
||
19 | arguments: |
||
20 | --debug enable debug messages |
||
21 | --pin=[PIN] provide SIM card PIN |
||
22 | }}} |
||
23 | 2 | Paul Kocialkowski | |
24 | Please run ipc-modemctrl like this (from host pc): |
||
25 | {{{ ./adb shell ipc-modemctrl start --pin=1234 }}} |
||
26 | |||
27 | assuming your SIM PIN is 1234. If you don't have any SIM pin, don't pass the --pin argument. |
||
28 | |||
29 | It should go like this: |
||
30 | {{{ |
||
31 | [I] Got SIM PIN! |
||
32 | [0] Starting modem on FMT client |
||
33 | [1] Starting modem_read_loop on FMT client |

52 | |||
53 | If something goes wrong, please add the {{{ --debug }}} argument to get in debug mode. |
