Using a FTDI FT2232D (Datasheet) in UART Mode for a dual RS-485 application I like to use some of the pins (e.g. not used handshake signals) as GPIOs (e.g. for switching on/of a termination resistor).

Does anybody know if this is supported in parallel to the VCP Driver for Linux? How would I access the pins separately?

The Bit bag modes only apply if NOT using the UART. All 8 lines are switched at the same time when changing the mode. You could use one if the 2 in bit bang and the other as UART. http://www.ftdichip.com/Support/Documents/AppNotes/AN232B-01_BitBang.pdf
