Hi All, Just to let you know the initial support for multiplexing has been added to oFono. The multiplexer infrastructure is fully customizable through the use of drivers. Two drivers are currently supported, GSM 27.010 Basic and Advanced modes. The multiplexer is implemented in gatmux in the gatchat library. GAtMux provides a simple interface, and returns a fully functional GIOChannel for each multiplexer port. Thus it can easily be integrated with the existing GAtChat functionality, or used to read / write raw information (e.g. ppp frames) This will allow oFono to implement everything in the main oFono process, and not resort to a separate multiplexer daemon. The calypso modem plugin has been updated to take advantage of 4 multiplexer channels. Regards, -Denis
