I'll admit I'm kind of surprised at all of the users sticking up for RS-232.
I would've thought Abdul would be safe in abandoning his internal RS-232
data pathway between the Atmel and FTDI chip. What are some examples of
RS-232 hosts that need to talk to GPIB test equipment? Old/retired laptops
being used as dumb terminals? Legacy DOS apps that don't have any form of
USB support? Both?
