Looking at your log snippets I meanwhile had issues again and I'm now running on ppp. It behaves ok until it doesn't, so somehow the issues are back here as well. I am currently logging quite a lot so let's see what I figure out. ppp seems nice, I especially like pppctl to see status of the line. What I can't seem to figure out is how to send AT commands like AT!GSTATUS? on "demand" to the modem with pppctl, any ideas of how this would look like? Can't seem to find much on the topic, I think ppp & AT is a bit out of fashion for most. I see the GSTATUS in the log on startup but I would like to check frequency bands from time to time to see if it stays on the same or not. regards Adrian
