usb driver problem

Very nice writeup.


Given that you're using an emulated serial port, my guess is that you
won't have to fiddle with the handshaking lines. This is where a usb
breakout box would really come in handy. But depending on the
emulation, some of the things that might affect buffering would be the
odsr, octs, dtr, and rts lines. So I'd try something like this (watch
the line wraps):

set the serialControlString to "baud=9600 parity=n data=8 stop=1
odsr=on octs=on odtr=on orts=on"

Do note that if you need to set the serialControlString, rev will
*reset* the serial port before applying your settings. This is
annoying, counterproductive, and needless, but that's the way it is.
It's caused me to rule out rev for solutions before.

Can you talk to the Arduino from a terminal window?
