Product Overview

There's a good reason why we sell more Mac USB serial adapters than any other company. Our years of experience in making PCI serial cards for Macintosh make us much more knowledgeable about Macintosh serial technology.

We applied this expertise to produced the first USB serial adapter for Mac OS in October 1998. Now, as competitors finally introduce their initial solutions, we are leading the way with a second generation adapter which delivers faster speeds and broader compatibility!

The new USB Twin Serial Adapter supports ALL Apple StyleWriters, Apple Personal LaserWriters (300/LS models only), Epson Stylus Color Printers*, HP DeskWriters and serial HP DeskJets! Expanded compatibility is just one of enhancements included in the new USB Twin Serial Adapter. This new model also delivers faster performance -- allowing HP printers, for example, to print 4 times faster than our previous adapter.

* Due to limitations in Epson printer drivers, the modem slot is disabled when using an certain Epson printers on the USB Twin Serial Adapter.
