5.0 out of 5 starsNW147 NEW DELL RD02-D400 USB EXTERNAL 56K MODEM
By M. Patton on January 31, 2012
Verified Purchase
This is a late model hardware modem that I got to use my laptop running Linux. Most laptop modems are software and do not have Linux software code. This just works because it is self contained with a processor and memory. The Conexant chipset is used in alarm systems to dial out. Same for Windows machines. No extra software needed. Delivery was quick too.

5.0 out of 5 starsWorks Perfect With Linux (what else is new?)
By R. Seehoffer on April 26, 2012
Verified Purchase
I've used Linux for about 2 years now, and frankly have found very little it will not do (except give me headaches from keeping 27 different antivirus/spyware/firewall/M$ Update/God-knows-what-else updated 12 times per month--but I digress...) Using this fax/modem was no exception. Linux Mint 10 recognized it immediately as soon as it was plugged in. I then downloaded efax and efax-gtk from the repositories, as well as gnome-ppp. I got this primarily as a fax, so that is what I played with first. efax-gtk is the 'front-end' or control panel for efax, and there is one setting change needed to make it work. Under 'File, then Settings, Modem tab, and finally Serial Device', change what is there to ttyACM0 exactly as typed here, including upper and lower case and the zero at the end. Under the Identity tab you can put in your name and your fax number. Click OK. That's it--read the Help pages and fax away. Gnome-ppp is a dial-up Internet access program, and all it needs is to 'detect' the modem--click 'detect' and you're set. It is smart enough to make the change above automatically during the detection process. Hope that helps somebody; thank you once again Amazon!

A small but possibly important addition for Linux users...

I'm now on Linux Mint 17 and everything still works. But I forgot to mention above that there needs to be a couple changes in the Linux "Users and Groups" settings to make this work. Under "Manage groups", add yourself as a user for group 'DIP', group 'Dialout', and I believe group 'Fax'. Save those changes, reboot, and THEN make the settings adjustments in each of the apps. The apps won't find the fax modem with these changes. Sorry 'bout that, 2 years late...

5.0 out of 5 starsIt Works
By Morronio on May 2, 2012
Verified Purchase
I rarely use my fax machine any more. So, I cancelled the dedicated fax line, recycled the fax machine, and bought this little gem of a modem. It's perfect for sending the occasional fax, just connect it to your PC and an analog phone line, then use Microsoft's Windows Fax & Scan. (It's in the Accessories folder.)
The one time cost of this modem is way cheaper than paying monthly online fax service fees, and it is much smaller and less expensive than any dedicated fax machine.
For those times when a company just won't accept an image via email, this is the way to go.
The Windows documentation indicates that if you leave the modem connected to a phone line, Windows Fax & Scan will receive faxes too. I'm not planning to use this method for receiving faxes and have not tested that process.

3.0 out of 5 starsDoes not install on Windows XP Pro
By Russule on April 17, 2012
Verified Purchase
The technical specs clearly state that this modem will work with Windows XP. I am running Win XP Pro on Dell Inspiron 530 and figured that a Dell modem should have no problems with Dell PC.

The modem would not install on my system, however. It appears that other people on the internet are having similar issues. I downloaded several driver software packages for this modem from Dell but they refused to install on my system. I finally gave up and returned it - too much hassle and modem comes with no instructions whatsoever.

I also tried to install it on a laptop running Win 7 and it installed without a hitch. I could send and receive a fax. So if you are running Win 7 this is probably a good choice but I would not recommend it for Win XP.

This modem is silent and I found that a bit disconcerting since I like to listen to the communication exchange but it is just my preference.

Works great as an external FAX with Windows 7. Just plug it and use it, no drivers or additional software required.

5.0 out of 5 starsIt works with lion, right out of the box. :)
By S.ahmed on April 18, 2012
Verified Purchase
No where it says its compatable with MAC, but it is, not only that, it also works with OS Lion.

After long time looking for a inexpensive lion supported Modem I bought this one. Lion supported modem runs for around $50.00 I didnt want to spend that much since i will only use it for fax. So i finally stop looking for those expensive modem and bought this for $16.00 bucks,thinking I will use it with widows in bootcamp to send fax, guess what, Lion recognized the modem too, I already started to send and receive fax without any problem. Folks who are looking for inexpensive modem for Mac os Lion, get this. Its good quality, from well known company, compact and last but not the least supported by os Lion. What more you could ask.:)

5.0 out of 5 starsIt's quiet, reliable, and just works as expected for me. I found it Great for $9.50 with Prime Shipping!
By Shishin Yamada on October 10, 2015
Verified Purchase
I have had excellent results with this $9.50 (prime shipping) Dell USB-FAX dongle on Windows 10.
Reading the other reviews, seems your mileage might vary.

Mine worked out-of-box, using VOIP (Google Voice with Obihai 100 adapter) for the past month.
I have also tested on our Ooma home phone service, with no problems.
I've sent more than 100 pages in the past month, with the largest file 26 pages in size, without a glitch (even if call-waiting clicks in, which surprised me).
I have only tested receiving 5 pages, which worked fine on VOIP.
Normally, I get my office inbound faxes via Maxemail.com (an e-fax service, so I don't need inbound fax on the modem, and I set Windows Fax & Scan to just outbound only, with ignore incoming phone calls).
It does briefly show callerID on windows 10 (although so fast in the corner I often miss it).

One reviewer complained about not being able to hear the fax-modem connection "handshake" noises. It is quiet when dialiing and connecting, but you can set Windows 10 fax & scan to sound a completion or failure chime. In any case, the few "failures" I found in windows fax & scan after 5 failed fax-send attempts spread 5 minutes apart, was either I put in fax # wrong, or they disconnected line (Windows F&S reported "busy line"). So those times, I just called with a phone handset to verify if there was a fax on the receiving fax #.For me, the majority of time I am dialing direct the same business faxes, so I use windows Fax & Scan contacts. After getting used to it, being quiet is not bad at all.

I have not tested the dial-up data-modem. I suppose it may be important is travelling abroad.Read more ›
