Thanks for you circuit analysis. I have many usb to serial adapters. I don't know the voltage provided by white but will probe it in the next few days.Google USB to serial cable.

Sounds like brown and yellow are simply device rx and tx albeit with a different voltage from the PC (or usb adapter). So the circuit is mearly a level shifter?
R1 and *R3*, that is.R1 and R2 is a voltage divider.
