I am new to DSL and just download and burn a CD, I got 2 problems. Firstly, during boot up my Philips LCD monitor can't adjust to the frequency, I must boot to 800x600 although the monitor is capable of 1024x768@60HZ. Secondly, I can't dial out, DSL can not recognize my US Robotics connected to COM1, I manually setup it up but still can't dial, no warning just nothing happen beside the dialer console shows up.
I have other systems installed on the same PC and all hardware are working fine, any idea ?

Thanks

You are having the same problem with your Robotics modem that I am having with my Conexant and Sportster modems.

Almost all 56K internal modems these days are software modems; they are deliberately designed to function only under Windows.

You might find drivers that will allow you to connect through your existing modem here:

< Linmodems: Linux Support for WinModems >

Hopefully someone with more knowledge than my illustrious self will have some answers for both of us on this thread:

< Debian based drivers for 56K soft modems?

? >

but an easier solution if you have another PC would be to use a crossover cable to share the internet connection on your Windows box; there is nothing to configure in DSL; just boot on up and type the URL into the address bar in DILLO.

Another possibility would be an external modem, but even external modems can be softmodems. I'll post another reply on this thread with specific brands and model numbers if I wind up going that route sucessfully, as this is a very common problem among us newbies.

'Kay; the guy who told me about this external serial modem positively raved about it, but please remember that I'm a n00b about a month into Linux with my Mandrake machine and a few weeks into dsl and I've never actually used this myself:

< Manufacturer's Info >

< A better place to order it >

hth many; I'm not a spammer and other folks have recommended ANY serial modem and suggested picking them up used on eBay; I do prefer internal modems for the folks I put together PCs for and have a personal interest in this issue so I'm not going to shut up without a serious warning and/or a slap on the wrist.

Thank guys, but my modem is a true serial hardware modem I used on M$ without driver, also on Suse no problem, but it is invisible to DSL, strange.

Maybe your "COM1" port is actually a different port in DSL.

Try dialing from

/dev/ttyS0
/dev/ttyS1
/dev/ttyS2
/dev/ttyS3

and see if any of these ports work.

When I use DSL with my US Robotics 5610 internal modem I set my modem as " /dev/ttyS4 ".

I use the same model modem in two different machines and both have to be set as stated above,hope this helps.

Thanks I will try. One more thing, I found that once I created a provider I can not remove it, I also can not add a new one, could you help me step by step to setup the dial up thanks.

I just successfully dial out, but can't resolve host, my ISP uses dynmaic DNS, I also tried to use fixed one but still the same, and the line dropped about 1min. looks like I did not logon the network yet, I tried PAP and CHAP but the same. When I ping I got access denied error, and I don't know the root password.

Sounds like you are getting closer to connecting to your ISP. It would seem that if you have filled in all of the info correctly in PPP Dial you should be all set.Keep trying and you should be able set up another account also.I'll give it a try here and see what happens.

EDIT> just tried to set up another connection and was successful.When I selected "Hangup" from PPP Dial and then selected to configure another connection the "provider" box was blank in PPP Dial. I am using DSL 0.9.3 at the moment from a hard drive install.

I tried the same CD on a DHCP Lan workstation which has a fixed connection to the Internet, once boot up I can browse the net without any problem, it is just the dial up missing something.

PS. Do I have to track this topic every time to receive notification, the box reset to uncheck every time.
