arduino leonardo

Hello everyone,
I have to communicate LabVIEW with Arduino micro.
When I send a information through  Serial.println("11"); to LabVIEW, it works
But when LabVIEW send something back to my micro Arduino, it doesn't work
However, when I used Arduino uno with the same program, I could send and receive program without any problem.
Could any one help me thanks

What exactly are you sending? Are you including s termination character such as a line feed? Can you send commands with another program such as the arduino ade or other terminal emulation program? You need to narrow the problem down. Are you using LIFA or LINX?
