I need to configure the modem part of a pcmcia multifunctionThe modem part of the card will not be eth0. That is strictly the
ethernet/modem card for my laptop. FC5 appears to correctly identify
most parameters but incorrectly identifies the modem part as an ethernet
device, eth1.
Here are the relevant parts of /etc/sysconfig/hwconf:
-
class: NETWORK
bus: PCMCIA
detached: 0
device: eth1
driver: serial_cs
desc: "3Com Corporation 3C562D/3C563D EtherLink III LAN+Modem PC Card"
vendorId: 0101

slot: 1

class: NETWORK
bus: PCMCIA
detached: 0
device: eth2
driver: 3c589_cs
desc: "3Com Corporation 3C562D/3C563D EtherLink III LAN+Modem PC Card"
network.hwaddr: 00:60:97:ee:c6:fb
vendorId: 0101
deviceId: 0562
function: 0
slot: 1
The system is correctly identifying the driver for the modem side of he
card. I may have helped get to this point by adding
card "3Com 3c562/3c563 Ethernet/Modem"
manfid 0x0101, 0x0562
bind "3c589_cs" to 0, "serial_cs" to 1
to /etc/pcmcia/config.opts as indicated in the material at
pcmcia-cs.sourceforge.net.
The problem is that the device eth1 on the modem side of the card
appears to be interfering with my ability to configure the ppp
connection in the Network Configuration tool. The tool tells me there
are no modems available and does not let me correct the eth1 to
something like ppp0, which is what it should be.
I tried to edit /etc/sysconfig/hwconf but it appears to be automatically
generated at boot time.
How do I get FC5 to correctly identify the dialup modem part of the
card?

Ethernet part of the card. I would expect the modem part of the card
to appear as a serial port, and you would have to specify the serial
port as part of the setup. If it is a hardware morem, then I would
expect it at something like /dev/ttyS2 or /dev/ttyS4, but it depends
on your hardware.

The modem part of the card should not show up as eth1, but the
configuration system is doing just that. The system is detecting the
card, assigning a serial driver to the modem, but declaring it to be an
ethernet device.
In my view there are several possibilities:
1. Some configuration file I am supposed to create to tell the system
how to configure the card. I noticed some alias statements
in /etc/modprobe.conf related to the card, including one that aliases
the serial driver serial_cs to eth1. I tried placing a file in
modprobe.d with a statement aliasing serial_cs to ppp0, but that didn't
help.
2. Some database with an error in it referenced by the configuration
software.
3. A bug in the pcmcia hardware detection and/or the network
configuration software. I've tried to look at the code in kudzu.py and
in system-config-network to see if I can find a bug. If there is a bug,
that's where it probably would be, and I see a lot of relevant
statements, but the code is too complicated for me to easily understand.
