Hello,

When connecting again to GPRS / PPP, after an Internet connection has been closed previously, the connection seems to fail. It looks like the ofono_modem serial data channel is completely closed when a PPP connection is shut down. I'm using a Telit Modem, which provides several serial ports, and am right now using separate serials for the AT chat and the data/PPP; for this reason, the AT chat continues working, but the data channel is dead.

My question is, is it somehow necessary to re-initialise the modem data serial channel after a PPP connection? Or could there be a conceptual problem that I have overlooked?

Many thanks & greetings       August
