If you have an inverted TTL serial signal then you can connect it straight
to n RS-232 port and there is a very good change it will "just work".  They
call it "TTL level RS-232".   BUt if you want to reliable drive a long
cable it is best to level convert to true RS-232.   But today most "re-232"
is actually using zero and five volts.
