Folks,
The Linear Technologies LTC1323 AppleTalk IC within the Newton is
capable of RS-422, according to the datasheet at
http://www.linear.com/pc/downloadDocument.do?navId=H0,C1,C1007,C1018,P1062,D2643

Here are all the links I dug up with an hour or two of digging through
junk on Google. This is meant to initiate discussion rather than be
particularly insightful in and of itself. Feel free to lambaste, tar and
feather, etc. etc. me.

See. http://www.easysync.co.uk/index.html?lang=en-uk&target=d25.html This manufacturer is unique because they claim "Complete driver support for Windows XP, 2003, 2000, ME, 98, Linux, MAC-OS8,9,X" An Australian company, Interworld Electronics, makes the USB-422, a single-port USB to RS-422 adapter, although I suspect it's expensive, since there's no price. I put a call in to them to get a quote. see: http://www.ieci.com.au/products/Product_Page2.asp?Product_ID=2088 Alternatively, there is this two-port RS-232 model capable of RS-232 at 230kbps.
