bluetooth serial port issues

I have a bluetooh problem.
1.My hardware: Bluetooh Bee module, Arduino board, Eee PC
2.My Software: Accessport, Arduino IDE
3.My sketch:

char val; // variable to receive data from the serial port
int ledpin = 8; // LED connected to pin 48 (on-board LED)
void setup() {
pinMode(ledpin, OUTPUT); // pin 48 (on-board LED) as OUTPUT
Serial.begin(9600); // start serial communication at 9600bps
}
void loop() {
if( Serial.available() ) // if data is available to read
{
val = Serial.read(); // read it and store it in 'val'
}
if( val == 'H' ) // if 'H' was received
{
digitalWrite(ledpin, HIGH); // turn ON the LED
Serial.println('H', BYTE);
} else {
digitalWrite(ledpin, LOW); // otherwise turn it OFF
Serial.println('L',BYTE);
}
delay(100); // wait 100ms for next reading
}

4.My issues:
The LED can be turn on when I enter 'H' via Accessport, but I can't see the response character on Accessport. I make sure the baud rate(Accessport) is 9600 on COM8(bluetooth serial port).
Can anyone give me hints to solve this issue?

I solved my issues, but have another question,
Serial.read() is getting data from BT, but Serial.print() is not sending data out via BT, why?
