Hi Denis, I have sent some patches concerning UIM for CDMA modem but I think I am missing something around modem.c so you can give them up :) For the moment, "modem.c" is designed for GSM modem, SIM atom is watched to add a state watch to make modem progressing into pre_sim post_sim online states etc... However in the case of a CDMA modem we will have to watch another type of atom (UIM for instance) and make the modem progressing into the following states: pre_uim post_uim etc... So what would you suggest to introduce CDMA modem into oFono? Should we create another src/cdma_modem.c with its own watches, states and cdma_atoms? Or should we keep the current naming (e.g. pre_sim post_sim etc...) and change current api to create cdma modem? Something like: ofono_modem_create(cdma=true/false) that is called from udevng. Then this new modem would be tagged as cdma and we would look for UIM atom intstead of SIM atom in case of cdma modem. What do you think about it? Kind regards, Guillaume
