Any change needs doing with reference to the standard not modem specific
hacks. Chances are the modem is right about the PF bit and we perhaps are
not - but it's not an encoding dependant bit so the patch is certainly
wrong.
In this case:
5.4.3.1 says (of UI/UIH etc) 'both stations shall set the P bit to 0'
so the modem is right and we are wrong.
I think what is actually needed is to just remove the PF setting
completely for that function. Obviously the other modems don't care or
check the bit.
Thanks for the right analysis, I got lost in the specification and didn't
found this. I'll update the patch as per your comments and resend a v2.
While testing this, I met several problems with Telit modems. I didn't found
anything suspicious in the log.
I attach the log for the 2 following case :
- Simcom SIM300 : mux establish fine, pppd launch and the link establish (I
interrupted the process), a serial terminal can talk to the modem and get answer,
- Telit UC864E : mux establish fine, pppd blocks after sending AT, a serial
terminal can talk to the modem and get answer so I don't understand why chat
fails,
In the 2 cases, I'm using the same kernel, on the same model of ARM9 System On
Module, on the same UART (and I switched the SOM between Telit/Simcom boards
to be sure the problem doesn't come from here).
And in the 2 cases, pppd works fine on the physical serial link.
If you have any idea of where to search for the problem I can do some tests.
Thanks,
Eric
