Keyspan has released beta USB drivers for Mac OS X which are available for download from Keyspan's Web site.

The drivers enable its USB twin serial-adaptor and USB PDA adaptor to be used with Mac OS X. The drivers are an update of the developer "seed" that Keyspan released in September 2000. They include support for PPP (point-to-point-protocol) under Mac OS X using serial modems. They also include an installer.

Because this is beta software, support is available via email only.
