I've never, as yet personally, done USART without MAX232...but if the rest of the experts(read:Nigel and Wilksey) vouch for it, then I guess it's doable. So far I've used MAX and it works like a charm.

Don't be so sceptical!

It's a very old tried and tested technique - there's nothing really special about a max232, it just inverting and level shifting.
