 h1. 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 GPLv2+ at: https://github.com/morphis/libsamsung-ipc (master branch). 

 The library is mostly complete 

 h2. ipc-modemctrl 

 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: 
 <pre> 
 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 
 </pre> 

 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! 
 [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'
