I assume the question you are asking is how do I get the required
voltage to run rs232 ? If that is what you want then you could look at a
DC-DC converter, mamim do them from memory
http://dbserv.maxim-ic.com/PowerSupplies.cfm
Or if you don't heed a higher voltage for any other parts of you design
you could look at a rs232 driver with voltage conversion built in. Again
Maxim do loads of theses but I can't remember the part numbers, take a
look on the same site under interface.
