Hello All,I have ran DSL 1.1 (i know, i know its an old one) live on my system and wanted to try to connect via dialup to the internet. This unfortunately has been a woe of mine ever since I installed Red Hat 7.3 last year, and I have not been able to connect to the internet yet
So, I tried it on DSL and heres how it went, step by step:
1. I opened up the "Dial-Up PPP" Application and clicked "config"
2. I did "Create a new connection" and named it "intelos" after my ISP.
3. Chose Dynamic DNS (what is that?)
4. chose PAP authentication (what is that!?)
5. typed username.
6. typed password.
7. put 115200 for modem speed
8. chose "Tone" over "Pulse"
9. typed phone number (didn't include area code) <----problem?
10. I had it automatically identify my modem (didn't find one) winmodem? Is this the problem? I have a "Lucent Win Modem" thats the actuall name!
11. I gave up and manually put /dev/ttyS1 then I tried ttyS0 (no difference)
12. hit "Finished" and exited the config.
13. I dialed, here is the error output:
local2.err chat[625]: can't get terminal parameters: Input/Output Error
local2.err pppd[619]: Connect script failed
14. Then I let out a big sigh and shook my head...
15. then I wrote this!
You guys are my last hope!
Thanks in Advance,
Patrick

Your biggest problem is WinModem. That spells trouble in Linux. A win-modem is short for 'windows-modem' which is short for 'crap'! A winmodem is a 'fake' modem. It is not a hardware 'real' modem that linux likes.Look at this post, and choose a modem from here:

Good Luck! (with a 'real' hardware based modem you should have little to no problems)
If you are brave... and have a lot of time on your hands, there are ways to get a winmodem to work (sometimes). It's not impossible, but I personally would not bother.

Yes, I have tried to get my other modem to work with drivers in a tar.gz. It proved to be a pain because the instructions weren't right! 
Anyway thats a long story...Thanks for your help,
Patrick

People have always told me that I couldn't use my winmodem with Linux, and they have always been wrong. I have successfully used my Lucent/Agere WinModems in my various different computers with Red Hat 7.0, Red Hat 7.3, SuSE 8.1, SuSE 9.1 Pro, and Core Linux. I remember once walking into Best Buy or CompUSA; can't remember which, but it was a long time ago when linux was a new thing, and most people didn't know about it yet, and I was amazed that they were actually selling boxed versions of Red Hat and Mandrake and SuSE in a retail computer store, and the salesman, very surprised that someone was actually looking at the linux section and not just walking right on through it came up to me and started telling me all he knew about linux which wasn't much because he of course wanted to sell me something, and so I discussed linux with him, and he brought up the topic of modems, and told me in these exact words "you will never get a winmodem to work on linux; you might as well throw it away," then he proceeded to comment that "don't you think Linux is kind of weird?" as he walked on to the aisle stocked full of Windows XP boxes. I thought this was extremely humorous, as I was already using a winmodem and had been for a long time on Red Hat 7.0 publishers edition which I got free in a Linux for Dummies book. My point is, people always assume that you cannot use a winmodem or that it would be very difficult and not worth your time to use a winmodem on Linux, when this is absolutely not the case. With one simple download on your web browser, and 3 easy commands, <<./configure>>, <<make>> and <<make install>> (must be root), you can magically transform nearly any WinModem into what is called a LinModem. Just as was previously said, a WinModem is a software modem that requires special software to make it work correctly and cannot work correctly by its own hardware alone. So, why couldn't this software be created on Linux? It has been, and it works great.You can find all kinds of information about transforming your WinModem into a LinModem at:
< http://linmodems.org/ >
You can find the driver you need at:
< http://www.heby.de/ltmodem >
If I remember right, installation is just like installation of anything else on Linux:
tar -xzvf ltmodem-8.31a10.tar.gz
cd lt*
./configure
make
make install (must be done as root)
Installation may be slightly different than this, but shouldn't be too far different, and once you do <<cd lt*>> you might find a file called INSTALL or README in that directory which will tell you exactly how to compile and install the driver, plus probably how to use it too once you have installed it, as one or both of these files are generally included with most Linux software that you have to compile and install. This is all from memory though, so don't quote me as I haven't used a modem at all in a long time. I'm really actually quite surprised that DSL does not provide a ltmodem.dsl for this driver, as nearly every modern Linux distribution provides an RPM file that just installs the ltmodem driver for you precompiled. I know SuSE does. Because DSL does not, you will have to compile your driver from source. Once you get it compiled though it should work great. I have had no bad experiences with the ltmodem driver, and have used it with every modem I have ever had since it's hard to find a modem at any store that isn't a winmodem these days.

Afterthought. In order to compile nearly any driver you have to have your kernel source installed. Luckily, this is easy on DSL. Just open up MyDSL Browser and click on System and you should find a package called kernel-source.dsl or something similar. Install that before trying to install the ltmodem driver or you will have compilation problems.
