The UART chip is being emulated in software. Actually it's not the 'UART chip' that's emulated in software, it's the 'controller' microprocessor (often a Z-80). That is, it's the chip that interprets the 'AT' commands and controls the datapump (DSP) which is emulated in software. Generically, they're known as 'controllerless' modems. Nevertheless, they only come with Windows drivers to emulate the controller, and won't work in *any* Unix environment, including FreeBSD. Gary
