Legacy Hayes Support

 

Modems shipped by the former Hayes Corporation are deemed "legacy" modems. You have a legacy Hayes modem if one or more of the following apply:

  • You purchased the modem before June 11, 1999.*
  • The warranty information states repairs are performed in a location other than Boston.
  • The serial number (SN) does not contain "H08." Note: Most Hayes Corp. serial numbers contain an "A" prefix.

Zoom attempts to provide free firmware upgrades WHEN POSSIBLE to Hayes 56K modem owners who purchased products shipped by the Hayes Corporation. Unfortunately, Zoom does not have upgrade firmware for the many Hayes-produced products that are no longer produced by Zoom. In addition, because we did not design these products and have inadequate documentation regarding the design, we cannot guarantee that these files will function properly or at all when downloaded. For these reasons, all firmware downloads for products shipped by Hayes are entirely at customers' risk.

The drivers, INF files, and documents we have obtained are posted below. These files are provided as a courtesy only. We claim no responsibility to the accuracy of the information.

 
 

Drivers and INFs

If your modem model is not listed below, try using the driver/INF file for a similar model (e.g., the driver for 56K Model X may also work for 56K Model Y) or a Windows pre-installed Hayes or Standard driver. Windows XP has many pre-installed drivers.

For Mac OS, click here for more information and to download the Hayes modem script files for OT/PPP, ARA, and Internet Connect (OS X).

These files are self-extracting unless otherwise noted.
