They are when the modem was sending information too quickly to the
computer, and some information got lost. David's suggestion of lowering
the speed, to say 38400, is a good one. 57600 is just on the edge of what
the '030's can do. :-(

Yes, and it will always be the case. The problem is that dial on demand
keeps network connections open even when the modem gets disconnected. It
works as when the modem re-dials, it gets the same IP address it had
before. With dynamic addresses, that's not so. You'll get a different
address when you redial. :-(
