Hi all guys! I discovered osmething very funny, something I wasn't expecting. And when you'll read the story, for sure you will be in my same position! Let me know. Relying on the immense knowledge and kindness of Bjorn and you all, I gathered some infos about the device who made my life extremely interesting, and not easy. so - what protocol do you think it's embedded over ncm? QMI? <whatever>? ... the protocol seems to be AT. Yes guys - AT! And I could never imagine it looking at the .c driver from Huawei right now. Yes, I'm not extremely acute. But, let's go to the technical thing: ndisdup works. 1 - Detecting connection I could not look at device leds, so I brought an AM radio near it. when I give the ndisdup commad on the standard serial ports, nothing happen. 2 - Connecting to the network To connect to the network you use the normal ndisdup command over WDM. At least in my case, the firmware became unstable, extremely unstable, after some minutes. The normal serial ports, and the at^statqry commands are not aware of what's happening, but the connection is activve. to confirm this, I can say that the modem emits ndis^stats:... unsolicited messages, and becomes hot after a while. Here is what happens: echo is never activated on this at port, even with ATE1 command.
