How is this done? It isn't. There are a wide variety of USB <-> Serial adapters, each using their own proprietary protocol (unlike the more sane area of storage devices which mostly implement the mass-storage class). In this case you have a small amount of luck, in that you've bought one of the more open devices. There's Linux support at http://ftdi-usb-sio.sourceforge.net/ and I have used information from there to write a trivial dumb-terminal which talks through the FreeBSD "ugen" device to access the port; this is more proof-of-concept rather than anything useful, but I've put it online in case of interest: http://www.arg1.demon.co.uk/freebsd.html To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hardware" in the body of the message
