Changes

*Got the system running again. The hard to find OS X driver for my [http://airlink101.com/download/ac-usbs.php Airlink101 AC-USBS (Serial Adapter)] was actually available from Prolific: http://www.prolific.com.tw/eng/downloads.asp?id=31. I think the airlink device must have the Prolific PL-2303 USB to I/O Port Controller inside. Finding a driver probably wouldn't be difficult if I bought some more recently manufactured usb-to-serial adapter, if people still manufacture those sorts of things. I need a serial adapter because the epson receipt printer has some old school serial connectivity on the back.
