UART 89S52<=>89S52

I am using two 89S52and I want to communicate between them via UART.
I have to 2 Question.
1. Did I have to use MAX232 in this case[communication through wire]?
2. If I use 413 MHz A.M. Modulator and Demodulator[TTL compatible]
Did have to use MAX232 in this case too.

Thanks.

No you don't have to use max232 at this case

It sounds like "what goes in, comes out" so in that case you don't need MAX232 either ..
