Multidrop mode in MQX on 52259

I'm trying to implement 9-bit multidrop mode UART under MQX.  I'm wondering what the best way to do this would be.

Can/should I modify the MCF_UARTx_UMR1, MCF_UARTx_UCR registers directly as needed ?  Or should I be trying to adjust the UART init_struct (MCF52XX_UART_SERIAL_INIT_STRUCT)?  Or is there some other better way?   Is MQX able to handle the multidrop bit for me?

I'm able to achieve the result I'm looking for by directly accessing the MCF_... registers, and the required code is minimal so I'm satisfied with this solution, but I guess I'm just concerned that doing it like this will confilct in some way with MQX.

Thanks for your input,
Angelo

PS. Sorry I'm reposting this - I posted in the Coldfire forum but I realized it should probably be in the MQX forum.
