I'd wondered about that, and realised that it is certainly something I'll
have to watch for. But I don't think it is the heart of the problem:
tcpdump tells me I'm getting (only) these....

Anyway, since I'm in Britain, and release 70 does not
support the "var unit size" that BT uses,
I decided to ignore the hangup problem until I got release 83 sorted...
(Hmmmm!)
Incidentally, one thing missing from the documentation that would be useful
for at least some people is some instructions about getting i4b to work
"dial on command" rather than "dial on demand". In other words, if I want
to explicitly tell it to connect and disconnect... Or at
least, to explicitly enable and disable DoD: a friend of mine who was
running DoD via a modem has warned me against windows machines propping
the link open... So what would be the recommended way of switching
between DoD and "off"? ifconfig-ing the link down?

Whoa! The man himself.
Thanks for the work you've put into i4b: it is good stuff (at least,
release 70 is:-) and your postcard will be forthcoming once I
can reboot without faffing with the phone plug! :-) :-)
Robert.
