You'd have to implement TCP/IP in userspace also, which wouldn't be too nic= e. = With recent kernels (2.6.29 and up), you'd rather want to create a new netw= ork = kernel namespace, containing the MMS interface and the one or few processes = sending or receiving MMS. That avoids the IP range conflicts while not needing to reimplement TCP/IP.= It = also still works if the modem exposes GPRS through sone kernel driver such = that you cannot cleanly send and receive IP packets in userspace anyway. = Currently, there aren't any in oFono, as both PPP and Phonet can provide IP = packets to userspace. But that does not mean there won't ever be any. -- = R=C3=A9mi Denis-Courmont http://www.remlab.net/ --===============7235252639509998743==--
