PCI modem/Linux/Serial Port
I recently installed Fedora Core 6, and I cannot
get my PCI modem to work. It is _not_ a winmodem
and did work on a machine running RedHat 7.2.
The output of "/sbin/lspci -vv " looks good:
01:08.0 Serial controller: 3Com Corp, Modem Division 56K FaxModem Model
5610 (rev 01) (prog-if 02 [16550])
Subsystem: 3Com Corp, Modem Division Unknown device 00d3
Control: I/O+ Mem- BusMaster- SpecCycle- MemWINV- VGASnoop- ParErr-
Stepping- SERR- FastB2B-
Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=medium >TAbort-
<TAbort- <MAbort- >SERR- <PERR-
Interrupt: pin A routed to IRQ 11
Region 0: I/O ports at a800 [size=8]
Capabilities: [dc] Power Management version 2
Flags: PMEClk- DSI- D1- D2+ AuxCurrent=0mA
PME(D0+,D1-,D2+,D3hot+,D3cold+)
Status: D0 PME-Enable- DSel=0 DScale=2 PME-
but I can't find the device file in /dev that corresponds
to the modem (and perhaps there is not one). Below is are
the results of "setserial":
# setserial -a /dev/ttyS0
Cannot get serial info: Invalid argument
# setserial -a /dev/ttyS1
/dev/ttyS1: No such device or address
# setserial -a /dev/ttyS2
/dev/ttyS2: No such device or address
# setserial -a /dev/ttyS3
/dev/ttyS3: No such device or address
I have been reading David Lawyer's Modem-HOWTO, but
I am stumped. Can anyone help?
For completeness, here are the lines with the word
"serial" that are written to /var/log/messages on boot.

Have you tried manually setting up the serial port according to the info
form lspci? It looks to me like you could use:
setserial /dev/ttyS0 port 0xa800 irq 11 uart 16550
Do you have on-board serial ports too? In that case, those might be
ttyS0 and ttyS1, making your internal modem ttyS2. |

Search for 'tty' instead. There will be a line with your modem's PCI ID.
However, you have another problem - your serial driver appears not to
work. What motherboard chipset is this? In any event, you need to get
this fixed before you could proceed any further.

bingo. ttyS0 on my machines is always the external serial port.
sometimes the hardware detection figures things out, and links /dev/modem to
/dev/ttyS0. i don't use Redhat or PCI modems.
has the OP tried dmesg? |

Did you look at usr's website to see if it has an rpm for your type of
modem?
Unless you need the onboard serial ports, I would disable them and map
the modem to COM1. It might make the process a little easier.

No, I suggested you do exactly what I said. Like this: 'dmesg | grep
tty'. And post the output.

It is an ASUS M2N-E motherboard.
The Chipset is an NVIDIA nForce 570 Ultra MCP.

Well, since these errors are most likely due to a kernel bug, I suggest
upgrading the kernel to the most recent Fedora version (and apply all
other updates as well). I hope you have a faster internet connection than
that modem - the updates will probably be a couple of gigabytes if not
more. What is the output of 'uname -a'?

Another place to look is the /var/log/messages file, and search through
the boot messages for the serial driver. Yes that 3CP5610 should work
like a champ, but only if the kernel can find the darn thing. I'm not
using Fedora, but on your old RH7.2 box, you would have seen
Aug 21 16:23:27 Serial driver version 5.05c (2001-07-08) with MANY_PORTS
SHARE_IRQ SERIAL_PCI ISAPNP enabled
Aug 21 16:23:27 ttyS0 at 0x03f8 (irq = 4) is a 16550A
Aug 21 16:23:27 ttyS1 at 0x02f8 (irq = 3) is a 16550A
Aug 21 16:23:27 ttyS2 at 0xddf0 (irq = 11) is a 16550A

[compton ~]$ whatis dmesg
dmesg (8) - print or control the kernel ring buffer
[compton ~]$
which shows the _current_ contents of the ring buffer. As what you are
looking for is what is happening at boot time, you might take a hint
from the system initialization scripts - the bottom of rc.sysinit on
Red Hat derived boxes at least used to say
# Now that we have all of our basic modules loaded and the kernel going,
# let's dump the syslog ring somewhere so we can find it later
dmesg > /var/log/dmesg
and thus, /var/log/dmesg should have the ring buffer at the point where
the serial driver should be loaded, etc.

[compton ~]$ grep -c rpm fc6-updates.04.28.07
1290
[compton ~]$ awk '{ total +=$5 } ; END { print total }' fc6-updates.04.28.07
4.47867e+09
[compton ~]$
4.5 Gigs - but the fine print says you don't need anywhere near all of
that. In fact, the 39 'kde-i18n' packages alone total 290 Megs, while
updates for openoffice (219 packages totalling 2.07 Gigs) dwarfs that.
The latest kernel on the updates server is kernel-2.6.20-1.2944 dated
13 April.

Thanks to everyone who volunteered their time
to help me out.
I solved the problem by re-installing
Fedora Core 6, this time, without choosing
the "Virtualization" package, whatever that is.
On a custom install, under packages to choose,
is listed something called "Virtualization".
I thought 'why not, I'll install the software
and see what it is' but apparently, when
you choose to install this package, the
"xen" kernel is installed rather
than the "normal" kernel. And according
to the archives of the Fedora mailing list,
serial ports don't work with the "xen"
kernel.
I think the Fedora installer should have
been clearer.
Thanks again.
