Xircom Cardbus RBEM56G Modem Problem
Hi all,
I've got a Dell Inspiron 7500 running an up-to-date Debian-testing
system. I can't get the modem function of my Xircom Cardbus RBEM56G
10/100+Modem 56 PCMCIA card working. Network has always worked, but I've
never seen any evidence that the modem is working, based on three
things:
1) running "#cardctl ident" returns
Socket 0:
product info: "Xircom", "CardBus Ethernet 10/100 + Modem 56",
"CBEM56G", "1.03"
manfid: 0x0105, 0x0103
function: 6 (network)
Socket 1:
no product info available
i.e. no mention of any modem. Also interesting that the card is not
quite correctly recognised (being the RBEM56G, not the CBEM56G). Is this
relevant?
2) wvdial cannot autodetect any modems on my system
3) minicom does not give me the standard: "at<RET>OK" response I'm
expecting (though I'm not sure which serial device I should be using).
However, I know the modem is okay because I am occasionally forced to
boot into Windows (this is a dual boot system) and it works fine there.
This problem has existed with kernels 2.2.17 through to (currently)
2.4.20 (from the linux kernel archives - not the Debian version). I've
installed the pcmcia modules (recompiled using kernel-package) and
pcmcia-cs package, but lsmod says no modules are running - I'm guessing
they're all in the kernel now.
An exerpt from my syslog upon card insertion is as follows:
Jan 23 21:55:26 a kernel: cs: cb_alloc(bus 2): vendor 0x115d, device
0x0003
Jan 23 21:55:26 a kernel: PCI: Enabling device 02:00.0 (0000 -> 0003)
Jan 23 21:55:26 a kernel: PCI: Setting latency timer of device 02:00.0
to 64
Jan 23 21:55:26 a kernel: eth0: Xircom cardbus revision 3 at irq 11
Jan 23 21:55:26 a kernel: PCI: Enabling device 02:00.1 (0000 -> 0003)
Jan 23 21:55:26 a /etc/hotplug/net.agent: invoke ifup eth0
Jan 23 21:55:26 a kernel: ttyS04 at port 0x4080 (irq = 11) is a 16550A
Jan 23 21:55:26 a kernel: xircom cardbus adaptor found, registering as
eth0, using irq 11
Jan 23 21:55:26 a cardmgr[249]: socket 0: CardBus hotplug device
Jan 23 21:55:26 a /etc/hotplug/pci.agent: ... no modules for PCI slot
02:00.0
Jan 23 21:55:26 a /etc/hotplug/pci.agent: ... no modules for PCI slot
02:00.1
Jan 23 21:55:27 a kernel: xircom_cb: Link status has changed
Jan 23 21:55:27 a kernel: xircom_cb: Link is 100 mbit
This makes it look like everything's going okay, so I'm a little
confused why it doesn't show up for any other programs.
I can provide other information, but am not currently sure what's
relevant.
What am I missing? (Incidentally, is ttyS04 is the same as ttyS4?)
Any assistance would be greatly appreciated.
Angus.
