Communication Settings on Programmable XBEE

I am using Programmable Xbee for one of the application. The Xbee has to communicate with the external serial port with the baud rate settings of 4800,7,E,2. I have Enabled the changes like baud rate and Parity. But i am not able to set the parameters like data bits and stop bit.
I have analysed the documents. It had been given the set options for 8 and 9 bits only.
Anyone can help me on this?

The FreeScale processor does not support the 7E2 option. It supports either 8 or 9 data bits only. But if you use Program control and bit banging then you can do it. But otherwise you can’t.
