This is what's frustrating. The hardware seems to work just fine...
I just gotta find how to introduce the right bits of hardware to each other.

I seem to have the same thing. If I remember correctly, the 2400 is the
same thing as a 3400, just the case is different, for all intents and purposes.

} hoever, I can't give you a clue if/how this would be possible.
As I said in my last message, I tried that with setserial with no joy.
Anyway, which docs do I try?
(Anyone who's reading the list...?)

}uhrm... actually, it should not. Atleast the pb2400 uses not an uart chip,
}but some bizarre Z8530 controller. check dmesg for lines like the following:
}PowerMac Z8530 serial driver version 2.0
}tty00 at 0xc4a0b020 (irq = 15) is a Z8530 ESCC, port = modem
}tty01 at 0xc4a12000 (irq = 16) is a Z8530 ESCC, port = IRDA
I have the same things... although I'll have to double check that the
interrupts are the same.
} Why is there isapnp running? AFAIK mac does not have an ISA bus, so
} why bothering? Possibly there is a mess-up with that?
No, I don't have an ISA bus. Don't know why it got installed.
Don't know how to uninstall it, either.
} Then, when the PCMCIA card initializes properls (both "beeps" are high and
} short - are they already?),
Yep. They have always been there.
} try using "minicom" package and tool; you
}can "speak" with your modem directly.
}(since if you haven't configured ppp yet properly, this might be another
}case for failure).
Minicom can communicate with the modem on any port, so I don't have anything there.
} ("echoed" to you by the modem). If you can't see
} anything, minicom didn't find the modem.
No echos. I wasn't getting anything.
Back to the drawing board.
