See the following tcpdump log (this is _all_ output -- nothing is printed after the timestamp). 00:00:04.301539 00:00:04.301630 00:00:14.300850 00:00:14.300941 00:00:24.300533 00:00:24.300625 00:00:34.300222 00:00:34.300312 (and so on) This could be some keep-alive mechanism -- I have no idea. I am quite sure that I did not see this on 1.4M or so, but I have changed ISPs meanwhile, so this could be the reason. Although this traffic does not keep the isdn connection up endlessly, it disturbs isdnd's idle time calculation (the connection is terminated at a time totally different from end_of_unit-early_hangup. What is the explanation for this behaviour, and what can I do to stop this traffic? (I have sent this to both the netbsd-help and the freebsd-isdn lists as I am not sure which party is the right addressee in this case.)
