TLV value runs over buffer

[Hans en Dory]

Hi everyone,

I am still struggling with this problem. I attached a piece of my log file again. This time, the connection was broke after the message. That means, the connection with my provider was still OK but no data was coming through. No DNS lookup took place, nothing happens until I unplug the dongle and make a new connection.

 problematic TLV, that would be great.  For ModemManager you

 Yes, that would be great.  I
 have my suspicions though: Huawei are fond
 of AT commands, and they tend to have a few
 unsolicted commands starting
 with ^.  24074
 happens to be 0x0a5e in little endian, or LF + ^ if
 decoded as ASCII.  Just a hunch...
