I don't know, since I need to kill the ppp connection to get access to the serial port, needn't I? > Mine is.

What kernel and pppd version are you running? I am usually running a fresh vanilla kernel and a rather current sid. I moved into a new apartment without broadband and had to use UMTS quite often since May 12 through June 5, when broadband was finally installed. The issue was present during the entire period. > 2) How often, after how much time of the connection running it usually > happens? Irregular intervals. Sometimes the connection is stable for hours, sometimes it dies after a few minutes. I also doubt that it is depending on traffic volume transported. > I have now two Option cards running: one is like this: > > ATI > Manufacturer: Option N.V. > Model: GlobeTrotter Fusion > Revision: 2.9.4 (Date: May 12 2005, Time: 10:55:21) > > (run "ATI" in minicom or picocom to see yours).

That link is a rather nice resource.
