| 5 | 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. |
||
| 6 | |||
| 7 | 1 | Paul Kocialkowski | libsamsung-ipc is shared between SHR and Replicant projects. It's used in both for the Nexus S. |

| 13 | |||
| 14 | |||
| 15 | 1 | Paul Kocialkowski | ipc-modemctrl is the tool that comes to test libsamsung-ipc. It currently implements basic functionalities (mostly SIM unlocking and network registration). |
| 16 | |||
| 17 | Usage: |
||
| 18 | 4 | Paul Kocialkowski | <pre> |
| 19 | 1 | Paul Kocialkowski | usage: ipc-modemctrl <command> |
| 20 | commands: |
||
| 21 | start bootstrap modem and start read loop |
||
| 22 | power-on power on the modem |
||
| 23 | power-off power off the modem |
||
| 24 | arguments: |
||
| 25 | 2 | Paul Kocialkowski | --debug enable debug messages |
| 26 | --pin=[PIN] provide SIM card PIN |
||
| 27 | 4 | Paul Kocialkowski | </pre> |
| 28 | 1 | Paul Kocialkowski | |
| 29 | Please run ipc-modemctrl like this (from host pc): |
||
| 30 | 4 | Paul Kocialkowski | <pre> |
| 31 | 1 | Paul Kocialkowski | |
| 32 | assuming your SIM PIN is 1234. If you don't have any SIM pin, don't pass the --pin argument. |
||
| 33 | |||
| 34 | It should go like this: |
||
| 35 | 4 | Paul Kocialkowski | <pre> |
