Internal... on a laptop... so a winmodem. :(

Yeah, I think you're right about the Winmodem. "setserial -g
/dev/ttyS*" showed just two recognized serial ports. Rebooting and
checking the BIOS told me that the second one was for the IR (InfraRed)
device. This laptop does have a regular serial port on it (I insisted
on it when I was shopping). I also have a PCMCIA slot and an old modem
card from a previous laptop, so that might be a better option than
wrestling with a winmodem. I don't know yet....

Did this (see above) and the "serial port" (or whatever) which the modem
is supposed to be connected to doesn't even show up. From what I've
gathered from the Serial-HOWTO, the modem (again, winmodem) is a PnP
("plug-n-play")... I'm guessing this thing (from "scanpci -v"):
pci bus 0x0000 cardnum 0x1f function 0x00: vendor 0x8086 device 0x24cc
Intel Corporation 82801DBM (ICH4-M) LPC Interface Bridge
STATUS 0x0280 COMMAND 0x010f
CLASS 0x06 0x01 0x00 REVISION 0x01
BIST 0x00 HEADER 0x80 LATENCY 0x00 CACHE 0x00
BYTE_0 0x01 BYTE_1 0x08 BYTE_2 0x00 BYTE_3 0x00
I've hunted around for a driver for this, got some indication that there
might be one, but I haven't found it yet.

I got exactly the same output. Rebooting and going into the BIOS, I
found that my IR card was bound to COM2 (ttyS1) and so moved it to COM4,
thinking maybe that would uncover the modem's port... but no.
I've got a couple dozen other things I need to do... and the person who
was going to fax me something is scanning the doc and attaching it to an
email, so I don't need the fax anymore. So I'm bagging this project for
now. Down the road, however, I want to set up an answering machine app
on this same machine, so I'll likely come back to all this. So in the
meantime, if anyone has any info on the driver which is going to light
up this winmodem, give me a little shout.
Thanks much to everyone who replied... all good tips... much appreciated.
