I have an old 56k modem that I am having to put in my sister's computer because unfortunately she is going to have to use dialup.

And also unfortunately, I do not have the back plate off of the modem to tell me which of the jack is the modem and which is the telephone pass thru.

Is the modem jack generally on the bottom or top ? From my memory I am guessing bottom but it has been a long time since I used a dialup modem.

Thanks.

There is no standard. Just plug it into one of the jacks and tell the modem to dial up the ISP: If it works, you're probably good.

Most of those jacks are in parallel i.e., either is the same, and using the modem doesn't cut out the phone.

If you were really looking for a specific answer, it would help a lot if you included the specific modem manufacturer and model number.

Without having a brand/model# to look up, I'd flip a quarter! :roll:

Edit: You're so much more polite than I am, Scott. :)

I'd say, it's the bottom jack. If that one doesn't work, then I'd try the top jack.

Or was it: try the top jack first, and then the bottom jack. I can never remember. I'm so confused. :p

Easy to tell .... If you have it in the correct jack, the modem will
be able to Dial Out .... use the built in modem test functions to
see if can get a Dial Tone .. if not, then use the other jack and
try again ... the modem model # would be a help as we can
then lookup the user manual for it.

This is "attempting" to be configured on Ubuntu/Linux so unfortunately, it is not quite that easy, or at least not for me !!!

Thanks.

Sucks to be you then, I guess. :D


It's almost certainly a generic Hayes compatible, for at least basic functionality. It's not rocket surgery. IF you have any specific questions, check with the folks at the *nix forum, I'm sure *someone* there knows what a modem looks like and how to configure it (but you'll still need to tell them the specific manufacturer and model, I betcha).

Lucent ENF656-PCIG-LUPR hmmm...
That's a "WinModem", right? Those were really popular at the end of the dial-up modem era. They required Windows to function because they are missing their own CPU. Or, at least, that was the deal at the time. Maybe Linux is "smarter" now.

The distribution that I am trying to use this does not seem to be !!!

I am assuming Ubuntu lacks a built-in drivers for this modem and so far I have not been able to find one that is for Linux. Plenty of windows but none for Linux. This is the thing that puts people off from switching to Linux. Probably going to have to go out and buy another modem for this machine or recommend that my sister stay with Windows.

I have been there already and the only thing I see there is a way to find out what modem I have and I already know that and the only other thing I get from here is a bunch of OLD dead links when I try to go to them.

But thanks anyway.

I am going to configure a machine with Windows (to make sure that this is a working modem) after lunch and I would be will to bet you money that the modem is configured just as soon as I get the O/S installed.

LOL. I remember the first time I installed Linux (RedHat 5.2). It took me the ENTIRE weekend to get it to connect to the Internet via modem and open up Netscape. There were all kinds of missing configuration files (or, at least, they were in the wrong location in Linux) that made it quite a challenge (for me, at least).

Thankfully, things seem to be a bit easier nowadays.

Well, it looks like I would have lost that bet.

I know it has been a long time since I installed and configured anything under Windows but I still could not get this *#@($*(@ modem to work. I am beginning to think that this is a defective modem. I did finally find a driver for it on Drvers.com and it still came up in the modem section of control panel as "non-functional".

Looks like time for a new modem.

Any suggestions on what would be a good dialup modem that I could have a pretty good chance of getting to work under Ubuntu/Linux ?

Thanks.

A Lucent/Agere modem will work automatically in XP or Vista.
Once installed windows will automatically install the drivers.
If it doesn't work, you're correct, probably time for a new modem.
.
Try: http://www.modemsite.com/56k/ltwin3.asp
for linux drivers for the Lucent modem.

Conventional wisdom is to use an External modem attached to a serial port.

I think that serial ports and parallel are still pretty common. Except on laptops. You can always add a cheap serial PCI card or even a Serial-to-USB cable if necessary. I doubt modems are very picky.
