https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D234578 Maurice J Niessen <du@hohlhupe.de> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |du@hohlhupe.de --- Comment #11 from Maurice J Niessen <du@hohlhupe.de> --- As Qingjun Wei already mentioned, you are discussing different issues here = and you are losing focus... The device 1199:9079 is not handled by u3g.ko to give us support (like /dev/ttyU*, /dev/cuaU*) for sending AT commands to it. AFAIK other methods = like MBIM, QMI and RMNET* aren=E2=80=99t supported in FreeBSD at all. Sending =E2=80=9Cmagic packets=E2=80=9D to specific OEM versions of 1199:90= 79 (and yes, mine says =E2=80=9Ccustomer: lenovo-laptop=E2=80=9D as well) to overcome the =E2= =80=9Clow power mode (LPM)/ FCC AUTH=E2=80=9D issue is something else. BUT for the =E2=80=9Cmagic=E2=80= =9D of a challenge/response authentication and setting FCC AUTH=3D0, it=E2=80=99s necessary to send AT = commands to our lovely 1199:9079. Dean already mentioned the =E2=80=9Cdescription=E2=80=9D in form of a pytho= n script how to do that =E2=80=9Cmagic=E2=80=9D. Within the years, the link has changed. It ca= n be found here now: https://github.com/bkerler/edl/blob/master/modem/sierrakeygen.py Patching the firmware of 1199:9079 with a black-boxed nvu-file from a Russian-speaking technical forum nvu-file to make it less specific, is something that I would neither do, nor recommend. This might be a workaroun= d, but like Ed Maste I want to know how to reproduce the nvu-file/fixes on my = own - generally. I love the fact, that my 1199:9079 is not able to produce high power signals (or even signals at all, so that ue0 gets an IP address for example) without =E2=80=9Cpermission=E2=80=9D. Sure=E2=80=A6 it=E2=80=99s m= ore an annoying =E2=80=9Cfeature=E2=80=9D, but much more important it=E2=80=99s not a bug of FreeBSD and nothing which needs to= be discussed in this topic/thread here (no offense). Yes, I know how to patch and build my own kernel=E2=80=A6 BUT you are speak= ing of a single line of =E2=80=9Ccode=E2=80=9D (more harmless definitions than real = code) in two files for years now. I would love to see those lines within FreeBSD 13 sources in= the nearer future. --=20 You are receiving this mail because: You are the assignee for the bug.=
