Hm. That makes perfect sense, of course... Unfortunately, I don't have the
docs for the modem, but it's an actual Hayes 14.4K, so I don't expect that
I'll have a hard time finding docs over the net.

The Flash ROM theory makes sense, although I don't know if the modem
actually has Flash ROM or not - either way, I'm telling the modem both
"atz" *and*, later, "at&f1", so it's definitely the default behaviour
of the modem to ignore the loss of carrier.

Thanks for the help!
