APC220 Ver 3.0 Not Communicating

I think I have done what all the startup sites suggest. I used the startup program:

int val = 0;
int ledPin = 13;
void setup()
{
Serial.begin(9600);
}

void loop()
{
val = Serial.read();
if (-1 != val) {
if (‘A’ == val || ‘a’ == val) {
Serial.println(“Hello from Arduino!”);
}else if (‘B’ == val || ‘b’ == val) {
digitalWrite(ledPin, HIGH);
delay(500);
digitalWrite(ledPin, LOW);
}
}
}

I loaded the Arduino from the pc with the TX and RX wires to the APC disconnected. Then disconnected the PC from the Arduino and started it with battery. I changed the pc from the original COM5 to the pc side APC, COM6. No communication either TX or RX. The program works because I can run it without the APC, just though the direct pc to Arduino board. I tested both modules on the pc using rc magic.
