Use Serial.write(val)

I am sending it as it is here but there may be errors

Serial.write((byte)0x81);
Serial.write((byte)0xee);
Serial.write((byte)0xf0);
Serial.write((byte)0x81);
Serial.write((byte)0xe0);

According to your chart you need to send a length (LEN) of zero

erial.write((byte)0x81);
Serial.write((byte)0xee);
Serial.write((byte)0xf0);
Serial.write((byte)0x00);
Serial.write((byte)0x81);
Serial.write((byte)0xe0);
