Hi guy's,

Presently i am using fedora 8 on my laptop. i tried configuring my Reliance datacard (ZTE MC315 CDMA 1X Reliance) for my internet connection.so i used wvdial.
my dmesg output
when i insert pcmica card


pccard: PCMCIA card inserted into slot 0
pcmcia: registering new device pcmcia0.0
pcmcia: request for exclusive IRQ could not be fulfilled.
pcmcia: the driver needs updating to supported shared IRQ lines.
ttyS3: detected caps 00000700 should be 00000100
0.0: ttyS3 at I/O 0x2e8 (irq = 16) is a 16C950/954

my wvdial configuration (/etc/wvdial.conf)

#[Dialer Reliance]
[Dialer Default]
Modem = /dev/ttyS3
Baud = 230400
SetVolume = 0
Dial-AT-OK ATDT Command =
Init1 = ATZ
FlowControl = Hardware (CRTSCTS)
Phone = #777
Username = (my mobile no)
Password = (my password)
New PPPD = yes
Carrier Check = no
Stupid Mode = 1

when i give wvdial it throw error like this

[root@station1 ~]# wvdial
--> WvDial: Internet dialer version 1.60
--> Warning: section [Dialer Defaults] does not exist in wvdial.conf.
--> Cannot open /dev/modem: No such file or directory
--> Cannot open /dev/modem: No such file or directory
--> Cannot open /dev/modem: No such file or directory
[root@station1 ~]#

when i give wvdial it's talking /dev/modem instead of /dev/ttyS3
so can any one help me how to solve this issue.

Thanks regards,
karthi

Look at the output of /var/log/messages when inserting the modem. I wonder if udev is creating the /dev/modem device. If so that may be what you want to use instead of /dev/ttyS3.

Before inserting the card, run "sudo tail -f /var/log/messages".
Running dmesg might give you the same results.

I check /var/log/messages as you said but it's uses the same /dev/ttyS3.
i tried putting /dev/modem for wvdial conf but i got the same error as i mentioned in first post. any idea why it's not talking.. any idea?
i tried using this command without using wvdial but it's incomplete can any one help me to complete the command..

sudo /usr/sbin/pppd connect '/usr/sbin/chat -v "" AT OK ATE1V1 OK AT+CTA=255 OK ATDT#777 CONNECT ""' /dev/ttyS1 115200 debug crtscts user (My mobile no) defaultroute

Why not make /dev/modem a symlink to /dev/ttyS3. Of course it’s not ideal, but it’s not too hard a work-around. You can even get udev to automate the process.

Look at the config file and the error message. The error message complains about [Dialer Defaults] not being found and you named the section [Dialer Default]. Unless the typo was made posting here fix that and you should be good.
