this is hard to believe. i had dapper on my system and had no problem dialing up. now with edgy i cannot dialup, i've tried pppconfig,wvdial and system-adminstration-networking. all to no avail.i have a diamond supra ext. serial modem connected to ttyS0. someone shed some light on this?

Check /dev/modem is present and pointing to /dev/ttyS0

Have you tried dialing the modem direct like this:

sudo echo "atdt 5551234" > /dev/ttyS0

... watch for the modem lights.

Have you tried: system > administration > networking -- modem, and configuring from there?

i've tried the networking app. ill try the other things you said. thank you.

ubuntu says there is not such directory as /dev/modem. also wvdial is writitng to /dev/null.

Well, that explains it. /dev/null is called the "bitbucket". It is where you write to when you want nothing to happen.

You want to create a symlink

ln -s /dev/ttyS0 /dev/modem

(This is a common convention, not essential but can simplify things.)

In terminal enter:

sudo wvdialconf (copy and paste output and command here)

cat /etc/wvdial.conf (copy and paste output with command here)

sudo gedit /etc/wvdial.conf (fill in your isp details)

wvdial (everything should go)

i did as you said. i uninstalled wvdial and reinstalled it. i also created a symbolic link. but wvdial is still writing to /dev/null. when i uninstalled wvdial, maybe i should have deleted the wvdial.conf files? also edgy will not let me edit /etc/ppp/peers, which might help.still no dialup.

I did not suggest you reinstall wvdial, I suggested you run sudo wvdialconf ... did you do this? I also asked you to post your wvdial.conf file here - you have not done this.

How can I help you if you will not follow advise?
Please reread my previous post carefully and follow all the instructions.

this is what i get when i do a sudo wvdialconf /etc/wvdial.conf:Scanning your serial ports for a modem.

... good, you have followed one part of my advise successfully. This means that everything went just fine. But what about the other parts of my advise?

I am getting tired of repeating myself - perhaps I am not being clear? If you do not understand something, please let me know and I will rephrase it.

Just to make things very clear, I've divided the advice into three (3) parts. Please complete all three parts before replying. Keep a record of what happens in each part. Your reply should include a record of what you did and what happened in the form of copied terminal input and output. If, for any reason, you are unable to complete all three parts, please explain. Otherwise I will know I am wasting my time and I will bother you no more. Thank you - the three parts follow...

Part 1:
Open a terminal and enter

cat /etc/wvdial.conf

You will get a lot of output that looks kinda like this... you copy your version and paste it here.

Part 2:
To make this conf file work, you need to change the last three lines. So, in terminal again, enter the following:

sudo gedit /etc/wvdial.conf

Using the editor, you need to remove the semi-colon ( from the start of those last three lines. Also remove everything in the chevrons (< >) as well as the chevrons. Replace all that with your details... i.e. instead of <Target Phone Number> you write in the phone number for your ISP, instead of <Password> you write your ISP account password, instead of <Your Login Name> you write the name of your account (eg. if you are normally joebloggs@yourisp.com, then your login name is "joebloggs").

Save the file, and exit.

Part 3:
In the terminal again, enter

wvdial

... copy the output and paste here.

Yes it doesn't work. It is a fault which Ubuntu should have seen before sending out edgy. Kppp doesn't work either.

I have not used earlier versions but my friends went back to Windoze because of this most basic of bugs.

heres it is[Dialer Defaults]
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0

i know what you are talking about. i have been using ubuntu since warty. thanks for your help.

My dialup is fine with Edgy. You are calling this a bug - do you have a reference for this?

AFAIK: The only thing not going seems to be the modem monitor applet.

after i enter the password, a message comes up saying, idle timeout

In your wvdial.conf, remove the line "stupidmode = on" and add a line "Stupid Mode = 1". Retry.

The initial dropped carrier, though, wasn't wvdial or anything linux related. It is your telephone line.

thanks. tell me something. how come dialup works in debian(etch) and windows?
