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?
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
echo "xxxxxxxxxxxxxxxxxxxxx" > /dev/ttyS4
and look for any activity. also check out the setserial
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?
I dont think having the modem connected to the phone line
should matter. It may be good to check interrupts
will show which are in use.
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
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!
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?
