Putting a MAX232 you will convert TTL levels (0-5v) to RS232 levels (-12/12V), so just a resistor divider will attenuate the voltages to your needs..

Hi,
Search for ICL7660 IC
It makes this conversion.
Best regards

I think the solution depends on the speed you require.

And why not use an MC1488 (rs232 driver) with +5V and -5V power supply ?
