Hi,
what do you want to know, the schematic or firmware? The circuit is very simple using max232.

Take care with this IC; It is obsolete.
Use MAX233 or SIP233 instead, because these fix 2 probles at MAX232 : Ripple at negative bias current, and big amount of external components.

At 99% of cases, MAX232 works fine, but at some PC you can´t comunicate so well.
