Using Console+UART with RS485

We have managed to get an RS485 working using the UART driver, however we had to use the callback funciton to toggle the Transmitter Enable to the RS485 Transceiver (expected this to have been built into driver).

Now we are trying to add the Console on to the UART, but it takes over the callback and we can no longer toggle the Transmitter Enable.

Any idea how we can make this work without re-writing your libraries ?
