The MAX3232 are guaranteed to run at data rates of 120kbps while maintaining RS-232 output levels. And it operates at a broader voltage than the 232 (3 - 5.5V) you can use this on both your 3.3 and 5V projects!

Application

Arduino Example

int val;
int ledpin=13;
int i;
void setup()
{
 Serial.begin(9600);
 pinMode(ledpin,OUTPUT);
}
void loop()
{
 val=Serial.read();
 if(val=='r')
 { 
   i++;
   digitalWrite(ledpin,HIGH);
   delay(250);
   digitalWrite(ledpin,LOW);
   delay(250);
   Serial.println(i);
 }
}
