RS232 Shield & Arduino Leonardo issue

I’ve problem getting the RS232 shield to work with an Arduino Leonardo.

The sample code “SoftwareSerial mySerial(7, 6)” doesn’t work.

I’m using SCL & SCA so Int2 & Int 3 are both taken up. How should I use the jumper to set the shield?

Following are my initialisation codes:

#include <SoftwareSerial.h>
SoftwareSerial mySerial(8, 6);
