This is the simple MAX231 RS-232C LED Circuit Diagram. Use a pair of
Maxim`s 5V-powered MAX231 RS-232C transmitters as drivers to obtain a
2-color LED. The transmitters require only a singleended, 5-V input to
generate ± 10 V internally.

Their outputs are short-circuit-proof and can supply as much as 10
mA-enough to drive most LEDs. Depending on which LED you select, their
currentlimiting feature might also eliminate the need for external
series resistors.
