I've used the FTDI232BM before. I somehow hoped it would be easier to get the specs now, but it seems I'm out of luck :-/ The good news is that the FTDI232R has a TXEN signal which can be used to driver a RS485 transceiver. That's exactly what I need, so I'll go for that chip. I'll see if I can find a FTDI-based USB/RS485 converter first to test communications at high baud rates.
