## Description

The USRobotics 56K* USB Softmodem delivers the performance and reliability USRobotics is known for in a compact, cost effective form factor. Broadly compatible with Windows including 64 bit and server systems, the modem uses the CPU of the host computer for high compression throughput due to direct parallel access. Features include ring detection and qualification - eliminating unintended wake-on-ring events due to activity on the phone line other than ringing, as well as handling pulse dial control to eliminate system timing dependencies common with soft modems. The USRobotics USB Softmodem is fully compatible with V.92 and lower rates, making it ideal for compact POS solutions that only require V.34.

## Questions & Answers

**Q: Can I send pdf files with this modem? Does it support windows 7 64 bit? Can I use it as a phone dialer and be able to speak hands free through the pc?**
A: This is a fax modem.  As such it will connect with a fax machine on the other end through a telephone line.  This modem supports Windows 7 but not Window 8 (unless something has changed), even though USR says 8 is supported.  Model 5639 does not support voice.  Go to the US Robotics web page, all the answers are there.

**Q: Does it have the "wake on ring" function (so that I can receive fax from stand-by/hibernation mode)?**
A: This is a really great question, so I will check and answer it... In Windows 8.1 (which should be the same for XP and up), has 2 checkboxes in Power Management under Device Manager.. One to allow the computer to turn off to save power (disabled by default), and Allow this device to wake the computer (checked by default.)So, Yes. and it appears to be activated by default (which I wasn't expecting.) and based on this, it can be changed as desired..However, without testing, I don't know (but highly doubt) if it would come out of hibernation, so it would have to be sleep, or a hibrid (if it works.) --OR-- have a power scheme that allows the processor to run 1% on it lowest, saving power, but allowing the modem and any answering machine/fax software the ability to run normally, and minimize the amount of heat coming from the computer..Hope this helps, and good luck.

**Q: Does this work with 32/64 XP?  Does it have driver disks?**
A: no it dosen't work i have a 32/64 xp and it did not come with a driver disc so don't know how it's suppose to work. it's say's built in but it won't dial up.

**Q: I have a dell inspiron 3647 windows 10, will this work for dial-up instead of paying for dsl?**
A: When I first upgraded to Windows 10 on my Lenovo Yoga 2, it did work. Since some updates, however, I am having trouble getting it to stay connected to the Internet, though I use it infrequently when I am having wifi problems. Sometimes with 8.1 the port would suddenly block the modem, but resetting dial-up connections would solve the problem. It seems more frequent with Windows 10. But then I am having battery driver incompatibility issues with Windows 10 since one of the updates that is affecting some other systems, so I can't be sure what the root cause of the modem troubles is. Sorry I couldn't give you a definitive answer!
