For sale I'm offering a lightly used and *was working last time I checked* USB modem. If you still have a land line, you can connect this to a USB port on your PC to send faxes from your PC. Last used from my Windows 10 PC, but it also worked from my older Windows 7 PC.
* Connects to your laptop or desktop computer to the Internet using a dial up Internet serice
* Only one phone line required—maintains Internet connection while receiving telephone calls
* Powered by your computer's USB port
* Box, installation guide, CD included
From the manufacturer's website, Trendnet.com:
* One side's a USB 2.0 port, the other side is an RJ-11 telephone port.
* Requires an RJ-11 (telephone line) splitter when sharing one line for both internet and telephone use (connect your computer and telephone to the RJ-11 splitter).
* The product is now discontinued.
