We're currently working on a userspace ppp implementation that will integrate with GAtChat. The goal here is to make it integrate well with the current multiplexed channel capability in GAtMux/GatChat and not need to involve an external daemon. > > After reading briefly the code from pppd, the implementation, for a > first draft, is pretty straight forward (w/o encryption, etc. in > userspace). "Just" dial the apn, and hand over the tty fd to ppp via ioctl. > Unfortunately it is not that simple. pppd requires a proper kernel file descriptor to hand off to the kernel ppp line discipline. In our userspace implementation that is not the case. 1 kernel file descriptor is shared by potentially many GAtChat channels using a multiplexing protocol. Hence why we can't reuse the kernel implementation. Regards, -Denis _______________________________________________ ofono mailing list ofono@ofono.org http://lists.ofono.org/listinfo/ofono
