The chip itself will work, but unfortunately you need a tristate buffer and an inverter in addition. Those parts are less than a dollar each, so you can put together something pretty easily using it, and if anyone wants, I can post part numbers and a wiring schematic...
Note that in addition to Rx and Tx you also need access to the CBUS2 pin, which is pin 13 on the 28-pin SSOP package chip.
The ATmega series micro-controllers can talk directly to the bus without requiring the buffering hardware, because you can enable/disable Tx and Rx individually under program control.
Don't try shorting the Tx and Rx pins on the FT232 - it will probably fry the chip...

Thanks, Jon. My "electronic skills" are very basic, but if you post it I will study it
