Its not the RFC1323 protocol that is the problem, I see that sup
communicates a lot with the server, then starts accessing disk for a long
time. Then it tries communicating again. In the meantime the ISDN router
has hung up so packets go nowhere and sup terminates.

sup -v -N -N -N -s was helpful with a systat iostat running in another
window.

A ping sup.no.netbsd.org in the background kept the line up.

Thankyou for your help!
