Hmm, I've been using USB-to-serial adapters and so far they've worked just fine. I plug the USB end of adapter into a Ubuntu box, see /dev/ttyUSB* appear, plug the serial end into the external serial device, and just use pyserial like with an actual serial port. I didn't realize there were issues with this. -- http://mail.python.org/mailman/listinfo/python-list
