Dialup Connection
 
I'm trying to setup an IBM Thinkpad 380XD for dialup internet connection using a Xircom 10/100 Ethernet+56k Modem combo cardbus.
When using Windows 98 the modem is listed on Port 5. In VectorLinux 2.0 all my com ports are listed from ttyS0-ttyS3.

When I do a dmesg command, I see this listed:

ttyS04 at port 0x4880(irq=11) is a 16550A

I don't see ttyS04 listed at all when I do an ls-l /dev/ttyS* command.

Is this telling me, port ttyS04, is the port it should be listed on? Isn't ports ttyS4 & ttyS04 two different ports?

How can I get the correct port for the modem connected?

Thnx.

For what its worth com5 on dos should be ttyS4 on linux.
I assume the modem is not a winmodem. If it has any status
lights try
echo "xxxxxxxxxxxxxxxxxxxxx" > /dev/ttyS4
and look for any activity. also check out the setserial
command.
Hope this is of use

Since I posted this thread, I created com port ttyS4 manually using the ./MAKEDEV command.

Now when I boot, I get to this message and it seems to hangs:

Configuring modem serial port: /dev/ttyS4

So I decided to pull the PCMCIA card out and put it back in quickly and linux continue to boot to the login screen.

Also while trying the port, I don't have the modem connected to the phone line at this time, would that cause it to hang at the Configuring serial port line?

Thnx.

I dont think having the modem connected to the phone line
should matter. It may be good to check interrupts
cat /proc/interrupts
will show which are in use.
setserial /dev/ttyS4
will show which the modem is using.
You can set the irq to 0 using setserial which will cause it to poll
worth an experiment but probably too slow for a modem

When I created the port, ttyS4, Vectorlinux hung at a screen showing, "configuring ttyS4. during bootup.

So I removed it. From reading the PCMCIA Howto, I think it stated that the modem should pick the first available port and make sure to have /dev/modem configured, which it is.

I"m still stuck on trying to configure this PCMCIA Xircom combo card. I have no idea exactly how to get this working.

Need more suggestions/ideas!

Thnx.

I'm still trying to get this pcmcia bus card working. Can someone tell me what is the command to start the card command for the modem?
