Review: Works better than other modems - We now recommend this modem to our customers to connect to our industrial product (often installed in areas with marginal phone lines). Nothing fancy required - we're just communicating at 9600 baud - but this modem just seems to work better than others for our application (e.g. compared to Zoom/Hayes external serial, Zoom USB, internal PC modem). The volume control is very handy for customers since they can turn volume up or down using the knob on the modem and don't have to mess around with control panel or AT command settings. ## Features - OS is compatible with Server 2012, Server 2011, Windows 8 64 bit, Win 8, Windows 7 64 bit, Win 7, Server 2008 64 bit, Server 2008, Vista 64 bit, Vista, Server 2003 64 bit, Server 2003, XP 64 bit, XP, NT 4.0, 2000, ME, 98, 95, 3.1, Linux and DOS - Operating Temperature conditions are 0 to 50 degrees C, Non-Operating Temperature conditions is -20 to 70 degrees C ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B003U9ZH7Y | | Best Sellers Rank | #1 in Computer Internal Modems | | Brand | USRobotics | | Color | red | | Compatible Devices | Personal Computer, Router | | Connectivity Technology | Serial | | Customer Reviews | 4.3 4.3 out of 5 stars (54) | | Data Transfer Rate | 56 Kbps | | Global Trade Identification Number | 00738168040995 | | Internet Service Provider | Xfinity, Cox, Spectrum, and others | | Item Weight | 8.64 ounces | | Manufacturer | US Robotics | | Maximum Downstream Data Transfer Rate | 0.06 Megabits Per Second | | Maximum Upstream Data Transfer Rate | 56 Kilobits Per Second | | Modem Type | Data Fax | | Number of Ethernet Ports | 1 | | Number of Ports | 5 | | UPC | 088037825896 132018262566 809385659922 778888433622 172302716016 100177266817 014444455524 086000307967 777785723515 012300421546 763616013917 882000440976 014445040385 738168040995 088037921536 809185808322 854587380044 851905134440 021111521208 999996719068 071020084356 523160906642 872040688681 168141495779 521227131624 807030489481 163120796816 809186264936 | | Unit Count | 1.0 Count | | Warranty Description | No Warranty | ## Product Details - **Brand:** USRobotics - **Color:** red - **Compatible Devices:** Personal Computer, Router - **Connectivity Technology:** Serial - **Internet service provider:** Xfinity, Cox, Spectrum, and others ## Images ![USR5686G 56K Serial Controller Faxmodem - Image 1](https://m.media-amazon.com/images/I/61pSZhwFXLL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great for my MIDI BBS computer *by S***D on November 16, 2025* Works great for my retro BBS. ### ⭐⭐⭐⭐⭐ Works better than other modems *by G***G on January 11, 2013* We now recommend this modem to our customers to connect to our industrial product (often installed in areas with marginal phone lines).
