Gene,
You could use one of the MAX232 chips by Maxim (others, such as analog devices make this
too)
Pretty cool family of chips - takes a logic level and translates to _+ RS232 levels,
using a single 5 or 3.3v supply and a internal charge pump.
Only required external parts are the .1 uf charge pump caps...
Randy
One comment on that. MAX232 requires 4 cap of 1.0 ?F (tantalum).
The "A" version (MAX232A) will work fine with 4 caps of 0.1 ?F.
